What is a caterpillar in a food chain?

A caterpillar is a primary consumer in a food chain, primarily feeding on leaves and plants. It plays a crucial role in transferring energy from producers (plants) to higher trophic levels, such as birds and other predators. As it grows, the caterpillar also serves as a food source for various animals, contributing to the ecosystem's balance. Ultimately, it transforms into a butterfly or moth, continuing its role in the food web as an adult.
