A natural habitat is an ecological or environmental area where a specific species lives. It is the place in nature that particular species calls home. To help picture what this means, think of a zoo.

Other algae are nontoxic, but clog the gills of fish and invertebrates or smother corals and submerged aquatic vegetation.
