Answer:
The correct answer is differential reproduction
Step-by-step explanation:
The different individual in a population tends to produce a different number of offspring and this difference in reproduction among them is called differential reproduction. This differential reproduction is responsible for producing more offsprings by some individuals.
Nature allows those individuals who are better suited in their environment to survive up to reproduction age and produce offspring and many of those individuals who are less adapted do not reach to reproduction age thereby produce less offspring.
