1 Reproduction is an important characteristic of living organisms. Explain

​

Reproduction is one of the most important characteristics of living beings, because -

- The existence of any species is dependent on the reproduction because no living being is immortal.

After death of a being of one generation,the existence of that died being is completed by the newborns of the next generation.

And,the birth of newborns of next generation is only possible by the reproduction.

- The variation and mutation in the biological characteristics is often necessary which is only possible by reproduction through many generations.

- When a living being becomes old, it's become unable to do normal tasks like collection of food, finding shelter etc,at that moment,the newborns of next generation do the necessary jobs.

And as mentioned before,these newborns are only possible due to reproduction.
