Ecology Ecology is the study of interactions between organisms and the living and non-living components of their environment. It involves collecting information about organisms and observing their life patterns as well. Ecology is a science that seeks to explain why patterns occur the way they do. Interdependence is a key component of biology‚ meaning that all the organism interact with one another in various ways. Its very crucial for organisms since they all depend on one another

A central organizing concept in biology is that life changes and develops through evolution‚ and that all life-forms known have a common origin.

This last universal common ancestor of all organisms is believed to have appeared about 3.5 billion years ago.[21] Biologists generally regard the universality and ubiquity of the genetic code as definitive
