1 Community Distribution EcologyCommunity Distribution
2 Ecosystem StabilityThe 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.
3 Ecosystems are in a constant state of change. Change can be rapid or slow depending onfluctuation in biotic or abiotic factors.
4 ToleranceTolerance 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.
5 Limiting Factors Limiting factors are any biotic or abiotic factors that restrict existence, reproduction, or distribution of organisms.
6 SuccessionSuccession - orderly, natural changes that take place in communities of an ecosystem over time.
7 Primary SuccessionPrimary succession is the colonization of new sites by communities of organisms.
8 Secondary SuccessionSecondary succession is the sequence of community changes that occur when a community is disrupted by natural disasters or human actions.
9 Climax CommunityThe 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.
