Food Chains and Food Webs in Ecosystems

The video tutorial explains how ecologists use diagrams to illustrate feeding relationships and energy transfer in ecosystems. It begins with a simple food chain example from the Galapagos Islands, showing energy flow from the sun to seaweed to marine iguanas. The tutorial then introduces the concept of food webs, which consist of multiple overlapping food chains, using the Florida Everglades as an example. It highlights the roles of producers, consumers, predators, and prey, emphasizing the interconnectedness of living organisms in complex ecosystems.
