L. DE Vere Burton has defined ECOLOGY as:

“The STUDY of relationships between living organisms and the environments in which they live is the science of Ecology.”

According to Eugene P. Odum:

“Ecology is the study of the relation of organisms or groups of organisms to their environment, or the science of the interrelations between living organisms and their environment.” Therefore, it may be concluded that ecology INVOLVES the totality of all the reciprocal interactions that take place between living organisms and their environment.
