Thousands of animals eat grass, including horses, cows, sheep, goats, bison, buffalo, deer, zebras, elk, wildebeest, kangaroos, grasshoppers, chickens, wild turkeys and even some fish, according to What Eats. Grass is one of the most important sources of nourishment for animals on the planet. Animals that eat grass are grazers, which literally translates into grass eaters, and most hoofed animals are grazers.

Animals that primarily eat grass are known as graminivores. Some carnivores, such as dogs and cats, eat grass occasionally to aid digestion. The scientific name for grass is graminoids, and it is the dominant vegetation in many habitats, such as grassland, salt-marsh, reed swamp and steppes.

Humans have many uses for grass. Foods made from grass include grain, sprouted grain, shoots and rhizomes, and drinks produced from grass include beer, whisky and vodka. Grass is also used as pasture for livestock. Thatch, paper, fuel, clothing, insulation, construction, sports turf and basket weaving can all be made from grass. It is one of the most versatile forms of life on earth and has adapted to rain forests, dry deserts and cold mountains — almost every region on Earth — and humans often use it for lawns and sports field turfs.
