Question

Although organisms die, their kind continues to live on earth. Which characteristic of living organisms makes this possible?
A. Respiration
B. Reproduction
C. Excretion
D. Movement

Answer 1

Hint: Continuity of life and survival are two interconnected topics of concern which are suggestive of the existence of huge biodiversity across the world. The only aim of each life form on earth is to maintain the continuity of its life forms for eternal generations. This may be related to the life cycle of each organism by which it makes sure that its kind continues to live on earth even if it dies during its life cycle.

Complete answer:
Option: A – Respiration is a vital life process by which organisms produce energy by breakdown of nutrients more often carbohydrates. So, this does not ensure continuity of life but it ensures survival.
Thus, option-A is not correct.
Option: B – Reproduction is the process by which organisms produce their progenies. This ensures continuity of life as even if the organism dies the progenies produced by that organism would ensure that its kind continues to live on earth.
Thus, option-B is correct.
Option: C – Excretion is a life process through which organisms remove toxic waste products produced in their bodies as a result of metabolism. Thus, it accounts for survival but it does not ensure continuity of life.
Thus, option-C is not correct.
Option: D – Movement or motility of any organism is not the way by which its kind continues to live on earth even after its death.
Thus, option-D is also not correct.

Therefore, Option B) Reproduction is the correct answer.

Note:
Reproduction is a biological process by which new genetically similar offsprings are produced by parent organisms. To replicate is to reproduce. It is a biological process in which an organism reproduces a biologically identical progeny. Reproduction allows and ensures the survival of species from generation to generation. It is the most important aspect of life on the planet.
