Why do we classify organisms??

OLEGan [10]

Answer: we classify organisms to group living beings who share the same characteristics or who have common attributes

Explanation: So, since the late '60s and based on the proposal of the researcher Robert Whittaker, most biologists group living beings into 5 large groups called Kingdoms, based mainly on three characteristics:

* type of cell,

* number of cells in each organism and

* the way of obtaining energy.

As a result, we could have 5 kingdoms; and these kingdoms are:

Monera, represented by the microorganisms of prokaryotic type known colloquially as "bacteria"

-Fungi, represented by mushrooms

-Plantae, the kingdom of the plants

-Animalia, the kingdom of the animals, and

-Protist, a very diverse group of organisms of eukaryotic type.
