Energy Flow and Ecosystem Roles

The video tutorial covers the concept of food chains, explaining how energy flows from one organism to another. It introduces the roles of producers, consumers, and decomposers, highlighting the process of photosynthesis and the types of consumers. The tutorial includes interactive games to reinforce learning, helping students identify different organisms' roles in the food chain.
