Food Web Dynamics in Ecosystems

This video tutorial explains the concept of food webs, focusing on the Shenandoah National Park ecosystem. It breaks down the complexity of food webs by examining the flow of matter through different organisms, starting with the persimmon tree. The video discusses the role of consumers like the black bear and gray fox, and the process of decomposition involving fungi. It emphasizes understanding the connections and matter flow within the ecosystem, providing a step-by-step analysis to help learners grasp the intricate relationships in food webs.
