Food Chain and Ecosystem Dynamics

The video reviews past science lessons, focusing on living things, their habitats, and food chains. It explains the roles of producers, consumers, and apex predators within a food chain. The teacher provides instructions for activities that involve analyzing food chains and understanding the relationships between living things and their environments. The lesson concludes with a summary and final activities to reinforce the concepts learned.
