1 Ecology Community Distribution

2 Ecosystem Stability The interrelationships and interdependencies of organisms affect the development of stable ecosystems – in other words the homeostasis of ecosystems. The interrelationships and interdependencies of organisms affect the development of stable ecosystems – in other words the homeostasis of ecosystems. The types of animal communities found in an ecosystem is dependent upon the kinds of plants and other producer organisms in that ecosystem. The types of animal communities found in an ecosystem is dependent upon the kinds of plants and other producer organisms in that ecosystem.

3 Ecosystems are in a constant state of change. Ecosystems are in a constant state of change. Change can be rapid or slow depending on Change can be rapid or slow depending on fluctuation in biotic or abiotic factors.

4 Tolerance Tolerance is the ability to withstand fluctuations in biotic and abiotic environmental factors. Biodiversity gives an ecosystem more tolerance. Biodiversity gives an ecosystem more tolerance. The greater the biodiversity, the healthier the ecosystem. The greater the biodiversity, the healthier the ecosystem.

5 Limiting Factors Limiting factors are any biotic or abiotic factors that restrict existence, reproduction, or distribution of organisms.

6 Succession Succession - orderly, natural changes that take place in communities of an ecosystem over time. Succession - orderly, natural changes that take place in communities of an ecosystem over time.

7 Primary Succession Primary succession is the colonization of new sites by communities of organisms. Primary succession is the colonization of new sites by communities of organisms.

8 Secondary Succession Secondary succession is the sequence of community changes that occur when a community is disrupted by natural disasters or human actions. Secondary succession is the sequence of community changes that occur when a community is disrupted by natural disasters or human actions.

9 Climax Community The final stable plant community is called a climax community. This community may reach a point of stability that can last for hundreds or thousands of years.
