Food Chain and Ecosystem Roles

The video explores the food chain, explaining how plants, herbivores, carnivores, and decomposers interact in nature. Plants are producers, creating food through photosynthesis. Herbivores, or primary consumers, eat plants. Carnivores, or secondary consumers, eat herbivores. Tertiary consumers, like eagles, are at the top of the food chain. Decomposers break down dead matter, recycling nutrients back into the soil. The food chain maintains ecological balance.

What is the primary role of the food chain in nature?

• To create new species
