What is what eats grass?

Grass is a primary food source for many animals, including herbivores such as cows, horses, sheep, and deer. These animals have evolved to have specialized digestive systems that allow them to efficiently extract nutrients from the tough, fibrous plant material.

Grass is also consumed by smaller animals such as rabbits, guinea pigs, and rodents. Insects, such as grasshoppers and caterpillars, also feed on grass, as do many species of birds.

In aquatic ecosystems, some species of fish and aquatic invertebrates feed on aquatic grasses and algae. Additionally, many species of insects and other invertebrates feed on grass roots and decomposing grass material.

Overall, grass serves as a vital source of energy and nutrition for a wide variety of organisms in ecosystems around the world.
