  • We all know that there are abundant of living organisms present on the earth. Many organisms are not identical to each other.

Introduction of Diversity in Living Organisms:

Look at your surroundings; you can see humans, birds, dogs, cockroaches, mouse, etc. We live in a diverse environment!

This diverse environment can be studied only if it is classified in a proper manner.

In this chapter, we will see how are these diverse organisms classified and how and who started classifying them on a different basis. The standard classification is discussed further and it really helps in understanding every species.

We will be focusing on the general characteristics in this chapter.
