Ecosystem Roles and Processes

The video explains how organisms in an ecosystem obtain energy, highlighting the roles of producers, consumers, and decomposers. Producers, mainly plants, use photosynthesis to create food. Consumers, including herbivores, carnivores, and omnivores, obtain energy by eating other organisms. Decomposers like bacteria and fungi break down dead matter, recycling nutrients back into the ecosystem. The video encourages viewers to explore their local ecosystems to identify these roles.
