A "Plant Eater," also known as an herbivore, is an animal that primarily consumes plants, including leaves, fruits, seeds, and roots. Common examples of plant eaters include cows, deer, and elephants. These animals have specialized digestive systems that help them break down tough plant materials, allowing them to extract the necessary nutrients for survival. Plant eaters play a crucial role in ecosystems by helping to maintain plant populations and promoting biodiversity. They often serve as prey for carnivores, contributing to the food chain. Additionally, their grazing habits can help shape the landscape, influencing the growth patterns of various plant species.
