The study of how organisms interact within the environment.
Ecology can be described as a holistic science because it can be explored really generally or in detail. For example, a coral reef is made up of many different organisms. You could study how one species interacts with the reef or you could study how the entire reef functions. (you have to study all areas to see how it works.) |
