When the gray wolf was removed, many animals died. The coyote was now the top predator so many of the populations of smaller animals like rodents and even animals like the antelope to decline. The elk population exploded so the grass and bushes were overgrazed and beavers had nothing to build dams and shelter with. Finally, scavengers like bears and vultures could not eat the remains provided by the gray wolves leftovers (because there were none.) The food chain was out of balance and it caused lots of harm to the ecosystem.

# data[].attributes.body
because the wolf is gone the food chain will be dramatically changed making deer over populate and with not wolf the deer would eat all the plants and tree leaves which would kill many animals they would starve with out food.

# data[].attributes.body
I at first I wonder why there were wolves in yellow stone till I found out that they were to keep the food change in line. The effect on having the wolves is to kill the elk so that elk doesn't eat all the grass so that the beavers could build homes.

# data[].attributes.body
The Wolf's prey population gets smaller, and they're prey's population increases. For example, the elk population ge
kts smaller, and the elk eats fewer grass, which in turn leaves beaver land to build.

# data[].attributes.body
One conclusion I can draw about gray wolves is that they keep Yellowstone in balance due to the fact that they hunt elk.

When the wolves were removed,the elk took over and ate all the plants.  Ruining the other animals habitats. When the wolf came, they hunted the elk and that brought things back to normal.

# data[].attributes.body
When the gray wolf was removed from Yellowstone the park went into chaos. This is true because the elk were over populated and overgrazed which meant that the beavers couldn't build homes or eat, the coyote became the apex predator which meant a decrease in the population in antelope, rodents and fox's and the scavengers couldn't find any of the wolves leftovers. So in the end I can conclude that the gray wolf and any biotic or abiotic organism has a reason for being and so it can not be taken out of it's ecosystems otherwise everything will go hay-wire.

# data[].attributes.body
After the gray wolf was removed, the elk started to get overpopulated and because of that, the beavers won't be able to build their shelters. And because the grey wolfs are eliminated, the coyotes are the main predators. But the coyotes don't eat everything that is on the info graphic so some of the other animals will get overpopulated.

# data[].attributes.body
The wolves in Yellowstone keep the ecosystem in balance. When the wolves were removed things got chaotic. Once the gray wolves were exterminated elks over populated and coyotes became the apex predator. When this happened beavers couldn't build their dams, and scavengers went hungry without the wolf leftovers.

# data[].attributes.body
The grey wolf is the rock that is holding the peace and stability in the ecosystem. When it was removed everything fell apart animals died because the elk ate all the trees the resource that the beavers needed to have as a shelter. Then everything fell out of place animals had no food and resources to live off of.

# data[].attributes.body
When the gray wolf was removed it effected everything. A lot of animals died during this time period because now they didn't have enough food. As a result the ecosystem was effected majorly. A lot of animals were effected by this in a bad way. Yes the animals weren't dying now but now their were more animals so they were eating up the ecosystem and eventually if the grey wolf didn't come back the ecosystem would have been gone.

# data[].attributes.body
I can tell that the whole ecosystem is connected. If one animal is removed, the whole ecosystem can majorly change and other animals can die. For example, when the gray wolf was removed, the cycle went crazy. There were too much elks that ate all the grass and trees so they died and the beavers died because the couldn't build dams and than the small animals got overpopulated. This shoes that one small change, can effect a whole ecosystem

# data[].attributes.body
When the gray wolf was removed it effected ecosystem. Many animals have died because of this problem. For an example: When one animal is removed it can effect all of the other animals. The elk was also a big problem, They ate all the trees and grass which effected the rest of the animals to die. This effected the beavers because now they didn't really have a natural habitat. All of this together caused the rest of the animals to have trouble with food.
It was like a domino effect, once something happens that can effect something else then that thing is going to effect other things, just like this ecosystem.

# data[].attributes.body
After the gray wolf was removed, the elk were overpopulated because of overgrazing. This was a major problem towards the other ecosystems and many animal populations as well. Because of this, all animals can be affected by one small act in the chain so it is like a domino effect or a chain reaction.

# data[].attributes.body
When the grey wolf was removed the entire environment changed. Elk populations exploded and overgrazed and the coyote became the top predator causing a huge impact on the numbers of antelope, foxes, and rodents. Also various numbers of scavenger species suffered due to no more year round kills from the wolves. In conclusion I can say that the Yellowstone's ecosystem was majorly impacted by the gray wolves.

# data[].attributes.body
An ecosystem depends on the gray wolf because the gray wolf helps keep the population of animals in track and balanced. So if we take away the gray wolf then other animals will over power and there will be to much of one kind of animal. If there is to much of one kind of animal then there might be less of another. This would happen because they would keep living off of one kind of animal and all of that kind would be hunted which would mess up the balance of each animal.

# data[].attributes.body
When one species gets removed from the food chain (the gray wolf) everything in that food chain goes out of order. When the wolfs were eliminated, nobody ate the elk causing the elk to overgraze. Since the elk were overgrazing, that effected the beavers by not letting them build dams which basically meant that lost their shelters. Then as the gray wolf lost it's place, the coyote took over as the top predator. That caused major changes because the populations of antelope, foxes, etc were all drastically decreasing. Knowing everything we've learned, all organisms are connected in someway, and if one of of the organisms go away, that can lead to a whole change which could lead to a lost of many species.

# data[].attributes.body
The action of removing the gray wolf affected all of Yellowstone, and also caused and left all of the organisms in disarray. The elks overgrazing caused them to have no food, and they resorted to what the beavers used as protection and homes. Without the top predator left the coyote, which wasn't nearly as strong as the wolf, as this led to the overpopulation of elks, and the decreasing population of antelopes and other small rodents, and these rodents were the food for scavengers which they couldn't live because they had no food.
Luckily, in 1995 they actually brought the wolf back, restoring the balance between all these animals and this just shows you how one animal can affect a whole ecosystem.

# data[].attributes.body
A conclusion that I can draw about wolves and their effect on resource availability in Yellowstone's ecosystem is that when the grey wolf is removed it will throw off the whole ecosystem meaning that it will come unbalanced. For Example, The Elk overpopulation and the beavers nearly become exigent if the grey wolf is removed. So the grey wolf keeps the food chain balanced and without any overpopulation and extinction!

# data[].attributes.body
An conclusion I can make is that the gray wolf holds the ecosystem together and makes it so there is not over population or extinction. I know this because the deer wouldn't have over populated because the wolfs would have killed most of them. Also, the scavenger species wouldn't have suffered because the wolf was one of the main predators to many animals.

# data[].attributes.body
In conclusion there effect is that if they don't kill certain animals others cant eat the left overs.
And if they cant eat leftovers then they die out and then the rest die out.

# data[].attributes.body
when the gray wolf left yellow stone the coyote was now the apex predator. With the wolf gone the elk population increased. the beavers were gone and their dams were destroyed by the river. But when the gray wolf returned the coyote was no longer the apex predator. With the gray wolf finally returned the Antelope and rodent population increased.

# data[].attributes.body
When the grey wolf was removed from Yellow Stone, the Elk had no predator, so their population exploded. All of the Elk had caused over grazing and prevented the beavers from building their dams. With no dams marshes turned into streams.

1. What can scientists learn by studying owl pellets?
2. Why is this a good method of study?

# data[].attributes.body
Scientists can learn about different ecosystems and diets of animals. Based on what they eat, you can tell what types of animals live in the same ecosystem as them. This is a good method of study because you wouldn't really have to go out and watch the owls and the ecosystem, you can just see what they eat/do when you observe the pellet.

# data[].attributes.body
Scientists can learn what the animals feed on and based on that, they can probably get clues of where they live. This is a good method because it can provide further information that can be useful in the future or even at the time.

# data[].attributes.body
Scientists can learn about what the owl eats without cutting the owl open to study how it digests. This method is a good way to study owls because owl pellets are trow up so you don't need to hurt the owl to find out what the owl eats and where the food is found in nature.

# data[].attributes.body
Scientists can learn the ecosystem around and the most common animal around the ecosystem that owls eat. This is a good method of study because it shows what an owl eats and the most common thing it eats.

something that a scientist learns from owl pellets is  what the diet of the owl and the population if it goes down or up. I think It is a good method of studying because they can study what they eat because they won't be able to find out what they eat by just the owl its self.e1

I think that scientists can learn about the different population changes. Also, studying owl pellets can give more advanced data to determine other facts and unidentified info
I think that this a good method of studying data and finding out info because it can give more data then the scientist's might have been searching for. Also the data is very accurate because the sample is coming straight form the animal.

From owl pellets, scientists can find out what the diet of the bird is, how much it has to eat, and what kind of bird it came from. (It's not always owls) This is a good method of study because scientists do not have to watch the bird to find out these answers, they can just look at the pellet.

# data[].attributes.body
They can learn what owls eat and what they eat most frequently. This is a good method of study because they can find out what the food chain looks like in that ecosystem. Also, they can find out if animals do not have a lot of their species alive still if the owl had a lot of bones of that animal.

# data[].attributes.body
The things that scientists can learn from studying owl pellets is the different environment or ecosystem that the organism lives in.  They can also dissect these pellets to learn more about the bird's habits and way of functioning through its complex food chain.
This is good to study because it lets these scientists know when the owls are eating at different times and places.

# data[].attributes.body
Scientists can learn what an owl or some kind of bird eats or what is the most popular prey for birds.
This is a good method of study because you get your own point of view of what they there prey is and, it basically has almost everything you want to observe about what these birds eat.

# data[].attributes.body
One thing that scientists can learn from owl pellets is the diet of the bird. They can also learn about the ecosystem based on the animals that the owl eats.

This is a good method of study because the pellet gives you nothing but the facts. It also is a first hand account and so you get everything that you want because it is directly linked to the animal.

# data[].attributes.body
1. What can scientist learn by studying owl pellets.
They can determine the types of owls by what they eat.
2. Why is this a good method of study?
This is a good method of study because scientist can learn things by studying owl pellets that they wouldn't be able to learn if they were studying owls.
