Food Chains and Ecosystem Roles

The video tutorial covers the roles of organisms in food chains, explaining how energy is transferred from producers to various types of consumers, including herbivores, carnivores, and omnivores. It provides examples of simple and complex food chains and introduces the concept of food webs. The lesson emphasizes the importance of producers in starting food chains and explains how energy flows through ecosystems. Students are encouraged to create their own food chains using given examples.
