Why is it important for scientists to classify organisms?

When scientists classify organisms, they are grouping organisms together so they can have a way to study them in a more efficient manner. Since there are millions of organisms on the Earth, it’s much easier to group them together for better research methods.

When scientists group together organisms, they decide what classification they will receive by their physical structure, DNA, biochemical similarities, evolutionary relationships and genetic similarities.

In the classification system used by the majority of the world, Linnaeus’s System of Classification, there are five kingdoms in which organisms  are classified. These five kingdoms are monera, protista, fungi, plant and animal.
