What is it? How Ecosystems Change A climax community is a community of organisms that have reached a stable stage of ecological succession. Describe it. Climax Communities Ecological Succession Climax communities are made up of plants and animals able to use ecosystem resources the most efficiently. Biomes Climax communities occur in many different biomes such as forests, deserts, grasslands, and coral reefs. What is it? Succession is the slow changes experienced by an ecosystem over time. Two Types Where does it occur? Scientists say that the two types of succession differ based on how and why the ecosystem changes occur. Secondary succession occurs in ecosystems that already have soil and once housed living organisms. Pioneer Species Pioneer species are the first species to colonize new or exposed rock. They are typically lichen or a kind of hearty plant, and they help create new soil from the rock. Primary Succession What is it? Primary succession occurs when new rock is created or exposed for colonization by living organisms. Secondary Succession Comparison to Primary Succession Secondary succession occurs faster than primary succession since the environment already has soil. When does it normally occur? Secondary succession occurs after dramatic events that kills much or all of community, such as natural disasters like wildfires.
