1.Answer: it is impossible for anyone to study all organisms individually. it is, therefore, necessary to place them into small or large groups on the basis of their similarities and differences. it also helps us to understand the interrelationship among different groups of organisms .that is why we classify organisms.

2.Answer: Any three examples of the range of variations in life forms are:
(i)LIFE SPAN: Every organisms has its own range of life span, e.g. mosquitoes live only for a few days while some pine trees live for a thousand years.
(ii) SIZE: The size also varies from organism to organism, eg. a microscopic bacteria is of a few nanometre in size while the blue whale is 30 metres length
(iii)COLOUR: colour variation exists from colourless or transparent worms to brightly. coloured flowers and birds.
