Habitat destruction is the process by which natural habitat is damaged or destroyed to such an extent that it no longer is capable of supporting the species and ecological communities that naturally occur there. Thus, habitat is a specie-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the therm habitat-type is more appropriate. If these needs are not met, the population will decrease until the resource rebounds. small flow of water flowing naturally from an underground water source. Habitat, by definition, is the environmental or ecological area being inhabited by any organism. Explore carrying capacity with these curated classroom resources.

If enough loose dirt slid down into the pond, it could fill up the pond and absorb the water, not leaving enough for the cattails to grow.
