Ecology Community Distribution
Ecosystem Stability • 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.
Ecosystems are in a constant state of change. • Change can be rapid or slow depending on fluctuation in biotic or abiotic factors.
Tolerance Tolerance is the ability to withstand fluctuations in biotic and abiotic environmental factors. • Biodiversity gives an ecosystem more tolerance. • The greater the biodiversity, the healthier the ecosystem.
Limiting Factors • Limiting factors are any biotic or abiotic factors that restrict existence, reproduction, or distribution of organisms.
Succession • Succession - orderly, natural changes that take place in communities of an ecosystem over time.
Primary Succession • Primary succession is the colonization of new sites by communities of organisms.
Secondary Succession • Secondary succession is the sequence of community changes that occur when a community is disrupted by natural disasters or human actions.
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.
