The natural habitat refers to the environment or ecosystem in which a particular species lives, grows and reproduces naturally. It is where an organism can find food, shelter, and mates for survival without any human intervention. The term also encompasses all physical and biological factors that make up the surroundings of an animal such as its terrain, climate, water sources, vegetation, and other wildlife species. In essence, it is where a creature feels most comfortable and at home in comparison to any human-made environment or captive conditions.
