What type of animal primarily grazes on grass and other plants for feed?

The correct answer is herbivores, which are animals that primarily consume grass and other plants for their dietary needs. Herbivores are uniquely adapted to digest plant material, which often includes cellulose, a complex carbohydrate found in plant cell walls that many other animals cannot break down effectively. This adaptation allows herbivores to thrive in environments where they can access abundant plant life.

Herbivores play a crucial role in the ecosystem by helping to regulate plant growth, dispersing seeds, and providing a food source for carnivores and omnivores. Additionally, they contribute to the nutrient cycle by breaking down plant matter and returning nutrients to the soil through their waste.

In contrast, carnivores primarily eat other animals, utilizing different adaptations for hunting and consuming flesh. Omnivores have a more varied diet that includes both plant and animal-based foods, which reflects a blend of adaptations suited for their mixed diet. Insectivores focus their diet on insects and other small invertebrates, following a completely different dietary pattern.
