Carrying capacity

Carrying capacity is the maximum population size of the species, that an environment can contain.Resources needed for survival are, water, food, shelter, and space.

The population of animals could change any time. For example, if a wild fire broke out in the mountains, many of the resources, like grass, might get destroyed. This would affect many animals such as the deer population. And if a water supply froze over or dried up, many deer would die because that is a resource every organism needs. Also if a tornado hit the mountains many birds would have to relocate because the trees would be torn down. This would cause the birds to go into a more enclosed space, being that they are all their, life would be more competitive. All the birds would need to fight for their resources, causing some birds to die, thus the population to decrease.

You can see in the picture bones. This may have been caused the drought that emptied the lake.

Limiting factors

Anything that affects the survival of an organism in an ecosystem.
Examples.
1.Disease
2.Hunting
3.Snowstorm
4.Wildfire
5.Tornado

Limiting factors can affect organisms in a predator/prey situation in many ways. In the mountains, bears eat many things, one of them being fish. If a fish got a disease and spread it among the other fish, soon most of the fish in that area would die out. This would cause the bears to either relocate or eat more of a different animal. This would not only have an affect on the fish population, but the population of the other species the  bear is eating. Also if the bears in that area all relocated then we would come back to the problem of space. Other limiting factors could come into play, like freezing, this would freeze the rive and cause the same outcome.

In this picture it shows the bear eating the fish, next you will see what happens to the river after the disease hit.

This is what happens when a disease spreads through the river.

Energy Roles

Related to photo/Mountains
Producer:Oak trees
Consumers:Squirrel,Beetle,Birds,Skunk,Raccoon,Frog,etc.
Decomposers: Mushrooms,Bacteria,Fungi,Worms

In the mountains, there are different tipes of consumers, such as herbivores,carnivores,omnivores, and scavengers.
Herbivores:Insects,california mule deer,elk,squirrels,big horn sheep,chipmunks,beavers,
Carnivores:black bears, raccoons,mountain lions
Omnivores:wolves,grey foxes,
Scavengers:cockroaches,opossum,
Each of the energy roles recieve its energy from what it eats. They only get 10% of it though.
Producers are vital to any ecosystem because 1, they give off oxygen which anamals need, and they feed the herbivores and omnivores, which the carnivores eat. So if the bottom of the pyramid fell it would caue a domino affect.

Food Webs and Food Webs

Food webs are more realistic than food chains because webs show more ways in wich an animal can go.For example in a food chain a hawk could only eat a rabbit, but in a web it will show what the rabbit ate, and what other animals the hawk can consume.
If you removed a population of lets say rabbits, than the fox who initialy ate rabbits and a few other animals like rats and squirrles, their population would decrease.It would also affect what the rabbit ate, their could end up bein an over population of that species.

Energy pyramids and Trophic levels

A pyramid is better than using a cube or cylinder because it shows that the closer you get to the top, the smaller it gets, this represents the energy.
Their is more producers(base)than there is carnivores(larger levels)because agains the producers get more energy so they flourish while the top barely gets any enrgy, so there isn't as much.

Decomposers

Decomposers are important in an ecosystem because they break down the decayed carcasus and remains of all organisms. If we didnt have them, all the nutrients plants get from decayed organisms would be gone and producers couldnt flourish as they do now.
You can find many decomposers in the mountains as you can anywhere else, some would be,worms,mushrooms,bacteria,fungus,insects,and more.

Adaptations

Adaptations are important because it allows organisms to evolve and mutate to become more suitable for their environment, for example a polar bear is white because of a mutation that helped it be a better hunter, also migration is one of the many examples.
Animals in my environment would need padded paws, camoflage, and being able to survive drastic climate changes.
A plant adaptation would be plants grow shorter to avoid being burrowed in by the snow.
If you were to move an organism to another habitat, it would later die out because it would not be fit for that sertain habitat. It would probabley not know where to find food and water, it might not also be able to find shelter.

Natural Selection

The process of the better adapted surviving and thriving, while the less adapted die out.
A tree in the summer gets alot of sun, but in the winter, ther is not as much sun to go around. trees will fight for sunlight, sometimes killing other trees roots, most of the time though trees will try to out grow one another. If multiple trees adapt and grow taller, than the ones left behind will die, thus the populationwould go down, but then boom again in the summer.
