i think they should be protected by the endangered species act because wolves might get extinct. wolves help people and the earth. Wolves help because they can stave off some climate change and play a role in maintaining healthy ecosystems. Also without wolves the ecosystem could go crazy

As said wolves kills actually help soil because every time they kill elk or other animals, it gives nitrogen and other nutrients.

if wolves in Yellow stone don't have capacity then the will most like not be able live or survive on there own. Worst case is that they have a wolf family and can't carrying enough capacity to hold them together.
if prey/predators don't have the nutrients from the ecosystem to survive then that will affect there population. Since wolves main food is elk, then if the elk are low then the wolves will have less and less food to eat. just like if there are storms, those storms can kill the coral and all the animals that eat coral will have less and less food to eat and it will be hard to live.so year that you go up then the population goes downs and if you put the percentages as 50% then most of them survive but some die. like i said with the wolves population, if wolves lower their population then their competition will have to find new prey or they will potentially start to lose less of there species and start to extinct.  some organisms  make their own food, so  other organisms can live with  organisms  and they can  live together and be a big family.

these things help animals live on earth,like food, water, and algae. but if you have storms or global warming then that can affect the population with a type of species.

There have been lots of population changes in the past 40 years for beavers. In 1921 they started to calculate how many colonies of beavers there are and the counted 25 colonies. In 1953 they found eight colonies in the northern range. The park-wide survey started in 1996 and counted 49 colonies and increased 127 by 2007, dropping 118 in 2009, and 112 in 2011. The park's population of beavers probably has grown in the last 15 years.

wolves habitats like forest, mountains, and desserts. they mainly eat meat and berries. they basically only need exercise, food, water, and shelter. mainly in a wolf pack there are 6-10 wolves. their lifespan is 5-6 years. in December of 2014, the population was 104 wolves in 11 packs. there are about 75 different packs in Yellowstone.

elk are the most abundant large animal in Yellowstone. Elk antlers are covered with fuzzy/thick coat sometimes referred as velvet. The grasslands habitat for elk is 10,000-20,000. less than 5,000 elk spend winter in the park. The population of elk in 1993-1994 was 15,000. Ever since the population of elk has been decreased. elk are herbivores meaning the eat plants. They prefer gibbon meadows, elk park, and Lamar valley.

moose are adapted to be in deeper snow than in any other part of Yellowstone. they usually will be found in small groups or found alone. their are less than 200 moose in Yellow stone. adults weighs about 1000 pounds if they are male. if they are female they weigh about 900 pounds. the reason for moose population to go down was due to loss of old growth forests surrounding the park, hunting outside the park, burning habitats, and predators.

death by predators or death by starvation.

# data[].attributes.body
if there is death by predators that means the environment is health and there is food to attack and then eat. if there is death by starvation then that means there is not enough food somewhere and and the food chain might break and the animals will die.

how to tell if an ecosystem is balanced 

# data[].attributes.body
how tell is if  when the natural animals and plants and non-living components are in harmony. With increasing pollution, change in migratory patterns, and rise of human population, many ecosystems are in danger of losing that harmony.

i don't think predators only kill sick or old prey because if they keep killing prey then they will probably not get the right nutrients to live. Also predators go for the most resourceful prey they can find.

i think the deer will be worse off without the wolves but they will be better off to. They will be worst off because they won't have meat laying around and they will have to kill their own prey. I think they will be better off because the wolves will not attack the deer and their population will be better if wolves will not think of them as prey.

how  physical and biological disruptions affect ecosystems

# data[].attributes.body
Rain,wind, and earthquakes are example of natural processes, which impact the ecosystem. humans also effect to ecosystem by  reducing habitat, over-hunting, broadcasting pesticides or fertilizers, and other influences. for example, streams and rivers can damage these tender ecosystem.

how does wolf population affect elk and willows population.

how does wolf population affect elk and willows population.

# data[].attributes.body
wolfs population affects elk because if wolf population goes down then elk population will go up and that is not good because elk will keep eat young trees and there will not be enough tree to create homes for animals.  wolfs population affect willows because wolves eat willows and that is not good because willows help with filter toxic waste and purify the soil. Also willows bark can be used as medicine to.
