Abiotic factors: non living factors in an ecosystem.

COLD TEMPS.                 





Carrying Capacity:

Definition: the number of people, other living organisms, or crops that a region can support without environmental degradation.

Example: A seal must rely on penguins to enter the ocean to eat them.

Limiting Factors & Predator Prey Relationships:

Definition: Items in an ecosystem that an organism must have to survive

Example(s) of limiting factors: A wolf must rely on other organisms to survive if there is no deer than the wolf will not survive.

Example(s) Predator Prey : Wolf(Predator) Eats the Deer(Prey)

Energy Roles:

Definition: each organism in an ecosystem has energy roles they provide needed energy for other roles

Producers get there food from the Sun, Consumers get there energy from lower level consumers or producers, decomposers get there energy from dead consumers

Producers start the energy transfers without them we would not get energy from the sun

Food Chains and Food Webs

Food Webs are more realistic than food Chains because... food webs show what would happen if an animal became extinct than how that would affect the other animals

If an animal died off than it would decrease the survival rate of the feeding organism

Trophic levels and Energy Pyramids:

The reason that producers are the BIGGEST(BASE) is because they are the most important part of the pyramid

The reason that Top predators are the smallest(top) is because there are not mny animals that feed on them and they take care of cleaning up the ecosystem



Definition: the turning of all or part of an organism in a particular direction in response to an external stimulus.

tropism is important for plants because they follow the external stimulus (Whats needed for them to survive)

Role of decomposers

Decomposers are vital to earth because without them we would be living in a pile of trash and dead organisms

Example of decomposers: FOX


Adaptations are needed for organisms so they can be able to survive and and camoflauge to catch prey

Plants need enough sun to survive in the arctic

Animals need to camoflauge so they dont get targeted by predators

If you place an organism in the arctic that came from the desert it would not survive because of the climate and the camoflauge it will not have

Natural Selection:

Definition: Natural selection is the gradual process by which heritable biological traits become either more or less common in a population as a function of the effect of inherited traits on the differential reproductive success of organisms interacting with their environment. It is a key mechanism of evolution.

Example: Polar Bear because it is camoflauged so it wont be as easy to see

I agree with everyone, you need to add pictures for your biotic and abiotic factors.
