(N/A) If predators are more in a group,it will lead to a rapid decrease in the population of prey on which the predators are dependent. Eventually,due to the lack of food,the predator population will also decline,potentially leading to the elimination of both populations.
$(b)$ Organisms that survive accidentally often possess certain variations or adaptations that provide a survival advantage. These individuals have a better chance to reproduce,continue their lineage,and increase their population size.
$(c)$ Organisms that are not able to adapt or survive in changing environmental conditions fail to reproduce and pass on their genes. Consequently,these individuals are eliminated from the population,which may eventually lead to the extinction of the species.
