Ecology is the study of organisms in relation to the surrounds in which they live. These surrounds are called the environment of organism. This environment is made up of many different components, include other/ living organisms and their effects, and purely physical features such as the climate and soil type. Ecologist, those who study/ecology are always aiming to/understand how an organism fits into its environment Ecology principles and applications J.L. Chapman and M.J.

Ecology can be defined as the study of relationships between organisms and the environment. Humans have been students of ecology as long as we have existed as a species.
