Question: As animals are heterotrophic organisms, the ability to move and find food is important. Movement on earth, for animals, occurs basically in three different environments (Air, land, or water). Each environment has the same forces working against movement (Friction and gravity). In no more than three sentences, choose ONE environment for movement and tell to what degree each force hinders movement and describe how those forces are overcome by the anatomical structure of animals that utilized that environment.
