![]() ![]() ![]() Horse owners usually feed horses a mixture of grasses called "hay." Some owners also feed their horses oats or corn. Instead of other animals, horses eat mainly grasses and plants. ![]() So where do horses end up on the food chain? Although people sometimes say they're “hungry enough to eat a horse," surely there aren't any animals out there brave enough - or hungry enough - to actually eat a horse… or are there?īelieve it or not, horses are prey animals. Still others, such as humans, eat both meats and plants. Some animals - called "carnivores" - eat only meat, while others - called "herbivores" - eat only plants. Of course, many animals are a source of food for other animals, too. Plants are a source of food for many animals. Sunlight allows plants to make food and grow by photosynthesis. The series of predator- prey relationships in an ecosystem is called a " food chain." Usually, all food chains start with the sun, which provides light and heat. If a cow eats grass, the cow would be the predator, and the grass would be the prey. However, the same terms can be applied to animal-plant relationships. People usually use the terms predator and prey to refer to animals. If a lizard eats the spider, though, it becomes prey. For example, a spider hunting for insects is a predator. Of course, some animals can be considered both predators and prey. Those that are eaten or hunted are called " prey." Examples of prey animals include zebras, fish and rabbits. Those that do the eating or hunting are called "predators." Examples of common predators include lions, bears and foxes. It is a simple fact of life that some species eat others.
