Climate: Climate is abiotic. It is abiotic because it is mostly caused by humans putting to much carbon and gas into the atmosphere.

•Scientists say that today’s warming is primarily caused by humans putting to much carbon into the atmosphere, like burning coal, oil, releasing gas into the air, and more. The gas gets trapped inside the atmosphere and kills the polar bears.
•Climate effects natural selection in the Arctic because with the polar bears, their feeding grounds are melting away as it gets hotter up there.
•Glaciers are melting in the North Pole.

Disease
Biotic

Disease affects natural Selection in a population becuase it spreads through breeding and through contact.

In an example I found it said that around 40/100 of the birds in a species will get the disease.

The next year those birds will breed and spread it and some of them will die. This affects the population by killing of the birds.

Natural disaster: abiotic

A natural disaster is a natural event such as a flood, earthquake, or hurricane that causes great damage or loss of life. Some reasons how this effects natural selection is that it can totally wipe out spices, it can destroy their environments, causing them to not have homes and resources. An example is a hurricane. A hurricane can destroy an environment and take out the land and animals living there causing some life to disappear or relate.

Deforestation
Biotic
- Deforestation takes away homes away from many kinds of animals such as birds, squirrels, insects, etc.
- 80% of land animals live in the forest, so when they are cut down, they have no homes.
- Deforestation creates climate change.
- Without the protection from trees, the soil can dry out and plays stop growing and die.
- Removing trees also removes the canopy which blocks the suns rays, so temperatures can be messed up, and make days very hot and make nights very cold.

Natural Disaster - Abiotic

A natural disaster is an abiotic natural advent such as a floos, earthquake, or hurricane that causes great damage or loss of life. A tornado can effect natural selection by completely destroying the habitat of animals, that then renders any adaptions they’ve made pointless as their habitat is gone. It can also destroy the food chain by killing many species of animals. Therefore causing a reset of the ecosystem.

Selective breeding
Biotic
Humans selectively breed animals to best adapt them to their environments for numerous reasons.  One reason is to help endangered animals survive, if a animal that is endangered isn’t already in a reserve, then breeders will atleast try to give them the best traits to help them survive and reproduce. Another reason humans would breed animals is to just give animals hem a better chance of survival. An example of this is, if a human wants to help a deer population survive in a polluted forest they could give that deer a darker fur color to increase its camouflage. This deer would then reproduce with other deers and there would eventually be a high amount of deer, that hunters might be able to start hunting them again.

Climate Change - Abiotic

Occurring in the North Poles

Glaciers are melting - polar bear’s habitats are being destroyed - polar bears die

Humans burn fossil fuels such as coal and natural gas creating greenhouse gases

Greenhouse gases are trapped in the atmosphere, causing global warming

Polar bears lose feeding ground and overheat

Migration
biotic
This happens when an areabecomes  too hospitable for an animal. The animal leaves it’s natural area to find a more hospitable enviorment. The animal then returns back when it’s home area is hospitable

Annual

Usually very large

The great migration, by trip savvy
The great migration is the biggest migration in the world, it is where zebra, wildebeest, and even gazelle. Follow a long path every year

Pollution-abiotic
Pollution effects people’s helath because exposure to pollution can cause cardiovascular and pulmonary disease. Studies show that air toxics are contributing to birth defects, reproductive failure, and disease in animals. This is how pollution effects the environment.

Invasive species: Abiotic
An invasive species can be any kind of abiotic organism. Invasive species have changed regions of South Africa from grasslands to scrubs it causes billions of dollars of damage each year and they are faced with hundreds of endangered species.

Disease

— Biotic

Disease can be spread in a population and without and adaptation to the it in future generations they could die or be required to move.

If new animals come into a existing community they could spread disease to other animals in the community.

Over Predation
Biotic
Over Predation is when predators over eat other animals that may make animals go extinct and the make population decrease.

Selective breeding/ artificial selection: biotic
Selective Brreding is when people breed animals for specific traits such as speed or strength.  An example of selective breeding is when farmers select cattle with beneficial traits like large in size or produce lots of milk. Another example is breeders select cats with desirable traits such as calmness and they want the cat to have a low amount of dandruff that may cause an allergic reaction. Selective breeding or artificial selection has beneficial ways and negative ways of effecting the environment. The negative way is it makes a risk of changing the elvolution of a species and because humans breed different plants and animals of particular traits this can lead to a risk. It effects the environment is a positive way because can influence the worlds food production like improving quality seeds, grains, and increases levels of protein in meat.

Pest Controls: abiotic

An example of how Pest Controls effect natural selection would be DDT and Bald Eagles. When DDT was used on crops it would get carried into nearby streams by winds. The DDT that’s in the Bald Eagles causes their eggs to have soft shells, and then when the Eagle sits on the eggs they break and the baby Eagle dies. This has cased the Bald Eagle population to become endangered.

Migration(Biotic)

Natural Selection is the process whereby organisms better adapted to their environment tend to survive and produce more offspring

The reason a population migrates is because they can’t survive in the population they live in now, a population migrates because they need to find more/better food or improved living and breeding conditions, so in a way migration effects natural selection because a population will move to a better environment so they will be able to survive and reproduce, a population will move so they will have a better chance of being naturally selected to move on

Selective/artificial breeding: biotic

Selective breeding can have both positive and negative effects. The positives are mainly towards humans those being stuff like having more food from cows that produce more meat, winning contests with show dogs and pigeons, and having an animal companion. The negatives are directed towards the animals , those being that most of the animals natural instincts aren’t as potent as they would be if naturally bred, meaning that if they were thrown into the wild they wouldn’t cope well. It affects natural selection in this way that the ones bred weak survive for being good for show or a good companion.

Selective breeding/ artificial biotic. Selective breeding is the process where humans take plants and animals with desired traits and breed them together to get the desired outcome. When use selective breeding you can damage the gene pool. A polydactyl cat is a genetically mutated breed where they have an extra toe on each foot, but there is a genetic condition called feline radial hypoplasia which can disable the cat because it causes underdeveloped or twisted forelegs.

Selective breeding is humans selecting animals to breed so that they can best adapt to our environment. One reason they do this is to make more of one kind of species and they will help because if they fine and breed 2 animals that are good in an environment then they can make more of the same animal because the population could be decreasing. Also the more animals they make the better because it makes a better selection for animals to eat other animal as well.

Hibernation - a decrease rate of activity and metabolism over seasons.

Biotic

Example - Grizzly Bear - By being dormant over winter survival rates of hibernating mammals increase due to the fact that they have limited exposure to the harsh outdoor conditions. This effects natural selection because of the fact that non hibernating animals do not have to compete for resources with other later mammals who hibernate. Small mammals who do not are also exposed to less predation. Overall, hibernation effects the balance of population over winter months.

Vaccinations:Biotic

Vaccinations can cause many side effects such as joint pain,autism,fever,but different side effects may occur to different organisms and animals. They all react differently to what they are given.

A vaccine essentially carries the weak version of a virus, and it is used so the immune system may adapt to the virus in case it will enter the immune system again.

In 2006 a vaccine plant named Merck had illegally discharged 25 gallons of cyanide into a river, and then all the cyanide flowed into the water treatment plant. That then reached the fish's habitat which killed off 1,000 fish.

If any of these chemical components would enter an environment it could cause all the species in that given area to inherit those side effects such as autism. This would cause entire species to essentially not be able to fully adapt to fending off a predator.

Those side effects would become apart of their genes at that point. Those chemical components could also enter other marine biomes such as areas as the ocean. This could cause all species in the ocean to inherit these side effects.

Land use:Abiotic/Biotic
Land use has an impact on our water and cause water pollution to the water that we use.The land use within the watershed has great impacts on the water quality of rivers. The water quality of rivers may degrade due to the changes in the land cover patterns within the watershed as human activities increase. Changes in the land cover and land management practices have been regarded as the key influencing factors behind the alteration of the hydrological system, which lead to the change in runoff as well as the water quality .
