Question

Reproduction is essential for living organism in order to
A. Keep the individual organism alive
B. Fulfill their energy requirement
C. Maintain growth
D. Continue the species generation after generation

Answer 1

Hint: Each and every organism can live only for a certain period of time the period from birth to the natural death of an organism which is called its lifespan . Isn't it interesting and intriguing to note that life span may be as short as a few days or as long as a few thousand years between these two extremes are the lifespan of most of the living organisms .

Complete answer:As we know whatever the lifespan of an organism is dead of every individual organism is a certainty that means no individual is immortal except single celled organisms . Given this reality have you ever wondered how vast numbers of plants and animal species have existed on Earth for several thousands of years ?
There must be some processes in living organisms that ensure this continuity . The continuity means the continuation of species generation after generation . That is reproduction, something that we take for granted . Reproduction is defined as a biological process in which an organisation gives rise to young ones offspring similar to itself. The offspring grow , mature and in turn produce new offspring . Thus there is a cycle of birth , growth and death .
Therefore reproduction is essential for living organisms in order to enable the continuity of species generation after generation .
So, the correct answer is ( D ).

Additional Information: There are two types of reproduction asexual and sexual .
Asexual reproduction involves a single parent and sexual reproduction involves participation of two parents of opposite sex .

Note: Sexual reproduction is more important than Asexual reproduction because genetic variation is created and inherited during sexual reproduction .
