10 points to the best answer.Explain how a deer has adapted to the biome: grassland?
Three conspicuous sets of adaptations:





[1] Hypsodonty: high-crowned cheek teeth, allowing for extra wear associated with eating abrasive grass





[2] Ruminant habit: having four-chambered stomachs, regurgitating cud from the first two chambers, and gut microbes that help digest cellulose





[3] Antipredator traits: to reduce risk of predation by large mammals in these open environments, they travel in groups, can trot quickly when chased, and often have coats that change in colour with the seasons
