047 - Ecosystems

Paul Andersen explains how ecosystems interact with biotic and abiotic factors. He explains and gives examples of food chains and food webs. He shows how limiting factors eventually leads to logistic growth. Real data from Yellowstone Park is used to show how populations interact. He ends the podcast by showing how human impacts can eventually lead to changes within an ecosystem.
