How does energy transfer in a food chain?

Back

Energy transfers from one organism to another in a food chain, starting from producers to primary consumers, then to secondary consumers, and so on.

What happens to a food web if a key species is removed?

Back

If a key species is removed, it can disrupt the balance of the food web, leading to population increases or decreases in other species.
