Energy Flow and Food Chains

The video tutorial explains the food chain, starting with the sun as the ultimate energy source. It covers producers, which are plants that make their own food through photosynthesis, and consumers, which include herbivores, omnivores, and carnivores. Decomposers play a crucial role by breaking down dead matter and returning nutrients to the soil. The tutorial emphasizes the flow of energy in a food chain, illustrated by arrows, and the roles of primary, secondary, and tertiary consumers.
