ฉันรักแปลภาษาKinds of habitats
Any place where organisms live is by definition a habitat. Your backyard, an empty lot, an agricultural field, a pristine mountain wilderness—all these are habitats for some group of organisms. Ecologists often find it useful to talk about kinds of habitats or to classify them into more or less general groupings. Habitats are typically classified on the basis of more or less obvious visual characteristics. Alpine meadows, conifer forests, marshes, lakes, desert scrub, and riparian zones along stream banks are all different habitats that you may be able to visualize from your own experience.
Sometimes habitat classifications have more to do with how the habitat functions than with its visual aspect. Although freshwater and saltwater marshes may appear similar superficially, each supports a different constellation of species. Along the California coastline at the ocean’s edge we can distinguish several zones that are functionally different. Above the high tide line there is a splash zone that only the highest ocean waves can reach. Below this is the intertidal zone that is alternately exposed and submerged with the ebb and flow of the tide. Deeper still is the subtidal zone, which is always submerged. Although all of these zones may occur within a few meters of each other, they are fundamentally different habitats for the organisms that live there and they support distinct assemblages of species.
