Ecology is the study of the relationship between plants and animals and their environment. Ecosystem is a community plus the nonliving environment surrounding it. Prairie dogs Prairie dogs are born in litters of four or five pups. They are born blind and deaf, and they only weigh up to half an ounce. Female prairie dogs live up to seven years, but males are lucky if they even live five years.
Prairie dogs eat seeds, flowers, and sometimes grasshoppers.
Prairie dogs are found in short grass prairies. Bison A bison has shapes like no other animal. It has a hump on its back that looks like that of a camel, yet it does not hold water. It's really a large shoulder muscle that holds up the bison s large head. The bison has a dark pile of hair on its head and a thick beard attached to its chin.
