All organisms residing at a different level of the food chain have some role or the other to play required for a balanced ecosystem. For example, plants and grass serve as food for the herbivores which serve as food for the carnivores and when these herbivores and carnivores die their dead bodies are devoured by microorganisms and insects living the soil and once these dead bodies are decomposed this enriches the soil which is essential for the plants.

Thus there is a need for a variety of animals and plants in a forest.
