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