Q:

Why is reproduction necessary?

A:

Reproduction is necessary for a species to continue existing. Individual organisms that belong to a species eventually die, but they are able to pass on their genetic information through production of offspring. Reproduction is one of the distinct characteristics of life, because only living creatures can beget other living creatures.

Animals reproduce either sexually or asexually. Sexual reproduction requires two organisms of opposite genders to mate and have their gametes form a zygote, the genetic makeup of which comes from the parent organisms. Asexual reproduction, on the other hand, requires only an individual organism to undergo cell division and produce offspring. Budding, regeneration and fragmentation are some forms of asexual reproduction. Parent organisms and their asexually reproduced offspring have identical genetic information.
