Why does mastery of biology depend on studies at different scales, from the small to the very large?

The biology mastery depend on studies at different scales, from the small to the very large because organisms that we study from micro scale micro-organisms to very large organisms such as elephants and whales.

When we talk about the subject biology it deals with all organisms that are present in this atmosphere, there are very diverse types and numbers of organisms ranging from a small microbe to a large mammal, hence mastering biology involves mastering all these organisms from micro to macro.

This is because biological life is very diverse from the very minute organisms such as microscopic bacteria to the very big organisms lie the elephant and human. They are all made of the basic unit of life called cells. Nonetheless, these cells work differently at these different levels even though the basics and molecules of life remain the same. Understanding biology at small and large scale is significant in understanding life and devising ways of improving life such as in medicine.
