Topic: Ecological Succession Learning Objective/Outcome: Keywords/Questions Notes What is succession? The normal, gradual changes that occur over time. How many types of succession are there? 2 When does primary succession occur? When new rock is formed or exposed and colonized by living organisms. What are pioneer species? The first living organisms to inhabit new or exposed rock. They help to create soil from the rock. What is secondary succession? Succession that occurs in a place that already has soil and was once home to living organisms. When does secondary succession typically occur? Following a disturbance that kills much or all of the community. What is a climax community? A community that has reached a stable stage of ecological succession. What do climax communities consist of? Plants and animals that use available resources most efficiently. Varies by biome. Summary There are two different ways that ecological succession may occur: primary and secondary succession. Once an ecosystem has reached a stable stage, it is called a climax community.
