Food Web Roles and Energy Flow

The video explains food webs, illustrating how energy flows through ecosystems. It starts with the sun's energy captured by plants through photosynthesis, which is then transferred to various organisms like flies, frogs, snakes, and aquatic creatures such as shrimp and fish. The video also highlights the role of consumers and predators, such as bears and hawks, in the food web, showing the interconnectedness of different species and the continuous flow of energy.
