Chapter 45, Problem 7SQ
Summary Introduction
Introduction: The branch of science that deals with the study of the geographic distribution of species is called biogeography. The total number of species present in a given area is called as species richness. The species present in a community can change over many generations. Some of these species alter the habitat, allowing other species to come and substitute them. These changes that take place in a community are collectively called as ecological succession. They are of two types, namely primary succession and secondary succession.
