Question

An inherent trait of organisms is the prodigality of reproduction; as a result, the number of organisms increases in a geometric proportion – justify the validity of the statement with two proper examples.

WBBSE Class X Life Science 03 (a) Heredity 02 Mark 2023

Answer

The prodigality of reproduction is an inherent trait of organisms. This means that organisms tend to reproduce in large numbers. This is because the chances of survival of an individual organism are low. By reproducing in large numbers, the organisms increase their chances of survival.
