Biological factors are circumstances in which a living organism is able to carry out life processes, explains the Marine Education Society of Australasia. These life processes include the ability to grow, consume, produce energy and reproduce. Fecundity is considered a biological factor because it deals with the ability to reproduce.
Abiotic factors are independent of an organism and usually include the nonliving aspects of an organism's environment. Abiotic factors differ from biological factors because they do not participate in carrying out basic life processes. An example of an abiotic factor is the amount of stones in Antarctica available to penguins to construct nests. Even though both abiotic factors and biological factors are both measurable, biological factors result in the growth, consumption, utilization or reproduction of living organisms.
