What are Food Chains | Learning Science

The video explains how energy flows through food chains, starting with the sun and moving through producers, consumers, and decomposers. It details the roles of producers, such as plants that use photosynthesis, and various consumers, including herbivores, omnivores, and carnivores. The video also highlights the importance of decomposers in recycling nutrients back into the ecosystem.
