Living organisms in a community and non living parts of its environment.

Group of various species that live in the habitat.

Living factors, Example Caribou, moss, flowers

Non-living factors, Example water, temp, rocks

The replacement of one community by another, at a single place over a period of time.

Development of a community in a area that has not previously supported life. Example volcanoes, glaciers, sand dunes

First organisms to appear in a new habitat, small and fast growing. Example weeds.

Replacement of species following a disruption of an existing community. Example fire, farming

Stable end point of succession remains constant for a long period. (Biome)

Large region characterized by a specific climate and certain kinds of plants and animal communities.

A relationship in which 2 different organism live in close association.

A relationship between 2 species in which both species benefit.

One species benefits an the other is neither helped nor harmed.

One organism feeds on another organism (host) which is harmed by the parasite.

One organism killing another for food.

Evolutionary adjustments between interacting members of an ecosystem

Organisms that break down the remains of plants and animals.

Organisms that carry out photosythesis

Organisms that eat other organisms instead of making ther own food

Consumers that eat mostly producers, eat mostly grass and leaves. Example is a cow, deer.

Consumer that eat mostly animals. Example is a hawk.

Consumer that eats both plants and animals. Example is a bear.

Each step in the flow of energy.

Flow of energy from one trophic level to the next.

Place where organisms or population of organisms live.

Organisms of the same species living in the same area

The number of species living in an ecosystem.

Process takes carbon from the atmosphere.

Process contributes to the formation of fossil fuels.

Example is remains of dead plants and animals.
