Forest Ecology - Hobcaw Barony
... Plants have a lot to do with where animals can live. That’s because animals rely on certain plants for food or shelter. The types of plants that grow in an area depend on the area’s climate, topography and soil. All organisms on Earth can be classified by species. A species is a group of organisms t ...
