Ecological Interactions

The study of the ecological interactions between living beings and their physical environment, including humans, is ecology. It aims to understand the crucial links between plants and animals and the world around them. Ecology also gives knowledge on the advantages of ecosystems and how we may use Earth resources to ensure that future generations have a healthy environment.
