b. Reproduction is linked to instability of a population.
c. Reproduction is linked to instability of a species.
d. None of the above.

Answer 1

Hint: The biological process by which an organism produces its new offspring is known as reproduction. It is the basic and fundamental feature for the formation of new individuals of the particular species on Earth. Each individual species survives as the result of reproduction.

Complete answer:
Reproduction is the process of producing new individuals of the same species from the pre-existing organism. The procreation of new offspring is obtained via sexual or asexual method. The particular species will disappear in time in the absence of reproduction. Thus, Reproduction is the only means to assure the survival of a species.

During the process of reproduction, DNA passes from one generation to the next. It contains the replication process of DNA, the carrier of genetic information, and its transmission from parent to new individual. The replication of DNA takes place with consistency but with minor variations. This consistency leads to stability of species.

The method of reproduction is responsible for providing stability to the population of species by giving birth to new individuals. The amount of birth rate must be at par with the rate of death to maintain the stability in the population of a species. By reproduction, organisms produce a large number of new individuals out of which several get perished and only some survive which ensures the continuity of species. These surviving organisms maintain a balance between the death ratios of naturally dying organisms. Therefore, it helps to replace the older population with the new population. Thus the population as a whole is not affected by reproduction and remains stable.

Hence, Reproduction plays a major role in the inheritance of genetic characters which passed on from one generation to another and thereby it is inevitable to maintain the stability of species.

Hence, the correct answer is option (A).

Note: Reproduction is essential for the survival of a species on earth. The population of species reproduce their new individuals by living in their suitable and comfortable places called niches in the ecosystem. There are certain genetic variations in the individual organisms of a species during reproduction. These variations enable them to survive even in dreadful environmental conditions (heat, cold etc.).
