How can we include decomposers and scavengers in food chains?

Decomposers and scavengers can be included in food chains by illustrating their role in breaking down organic matter and recycling nutrients back into the ecosystem. In a typical food chain, after primary consumers (herbivores) eat producers (plants), scavengers consume dead animals, while decomposers, like fungi and bacteria, break down both plant and animal remains. This process not only cleans up the environment but also enriches the soil, supporting plant growth, which in turn sustains the food chain. By integrating these organisms, we highlight the importance of all trophic levels in maintaining ecological balance.
