Chapter 60, Problem 7TY
Summary Introduction
Introduction: Habitat is defined as the closed geographical area that promotes the survival of a particular species. Some habitats promote the survival of a large variety of species. However, they are at the threat of being extinct, and these habitats are known as endangered habitats.
