प्रश्न
How does reproduction help in providing stability to populations of species?
उत्तर १
Reproduction is the process of producing new individuals of the same species by existing organisms of a species, so it helps in providing stability to the population of a species by giving birth to new individuals, as the rate of birth must be at par with the rate of death to provide stability to the population of a species.
उत्तर २
Every species has to constantly struggle for its survival. The rate of birth and death in a given population determines its stability. Birth rate and death rate should be approximately equal. Reproduction is a way to replenish the lost section of the population.
