2.Organisms that are best suited for survival in their environment will be able to compete for limited resources better than organisms that are not well suited to their environment.
3.Hibernation is a way animals conserve energy to survive adverse weather conditions or lack of food. It involves physiological changes such as a drop in body temperature and slowed metabolism.
4."survival of the fittest" is a popular term that refers to the process of natural selection, a mechanism that drives evolutionary change. Natural selection works by giving individuals who are better adapted to a given set of environmental conditions an advantage over those that are not as well adapted.
5.This led to Darwin developing his theory of adaptation.
Darwin's adaptation theory, also known as survival theory or survival of the fittest, ans states an organism's ability to adapt to changes in its environment and adjust accordingly over time
6.c
7.The similarities between different types of an organism can be explained by the theory that they all come from a common ancestor. The differences between them are due to changes over time that have developed through natural selection.
8.Natural selection is the process by which organisms which are not as well adapted to their environment do not survive long enough to pass their less favorable traits on to the next generation of their species.
9.d
10.migration, hibernation, dormancy, camouflage, and estivation
