A large variety of plants, animals, and microbes found on earth and they differ in size, shape, colour, habitat, and many other characteristics. So, studying each of them is impossible. Therefore, scientists have devised mechanisms to classify all living organisms on certain rules and principles that allow identification, nomenclature, and finally classification of an organism.
For example, based on presence of three pairs of legs and 2 pairs of wings, an organism is identified as an insect, it will be given a scientific name and then grouped with other similar organisms. Thus, various groups or taxon include organisms based on their similarity and differences.
Therefore, the biological classification helps in revealing the relationship between various organisms. It also helps in making study of organisms easy and organized.

Is the answer is rightâ
This answer says just the opposite of answer 6th. Please correct it
For question number seven, the last paragraph contradicts with the answer given in the previous question (i.e. number 6). So, do plants become greener in the shade, or do they turn yellow? Because, the previous question's answer states that if the chlorophyll pigments don't receive enough light, then they stop production and break down, hence allowing the xanthophyll and carotenoids to dominate, and turning the leaves yellow; but here it's stating that leaves in the shade will have MORE chlorophyll pigments to compromise for the lack of light. But, aren't they supposed to diminish in sunlight?
