Give three examples of the range of variations that you see in life form around you.
Range of Variations:
(i) Life span- insects live for a few days whereas cow, dog and humans etc. live for many years.
(ii) body structure—Organisms like cows, insects plants and humans have different body structures.
(iii) Size—Some organisms are small while the others are big. Even different plants are of different sizes
How are the criteria for deciding divisions in plants different from the criteria for deciding the subgroups among animals?
Explain the basis for grouping organisms into five kingdoms.
How would you choose between two characteristics to be used for developing a hierarchy in classification?
Explain how animals in vertebrata are classified into further subgroups.
