<h3>What is a habitat?</h3>
The term "habitat" in ecology refers to a region's collection of biotic, physical, and resource elements that are present to support a specific species' ability to survive and reproduce. It is possible to think of a species' habitat as the outward representation of its biological niche. As a result, "habitat" refers to a particular species, which is fundamentally distinct from ideas like "environment" or "vegetation assemblages," for which the term "habitat-type" is more applicable.
