Why is the productivity poor in the deeper parts of the ocean?
What will be an ideal response?
In the deeper parts of the ocean, sunlight only influences the activities happening near the surface since
the sunlight does not penetrate deep into the water. In addition, many nutrients sink to the bottom of
the ocean. This impacts productivity greatly since both sunlight and nutrients are necessary to improve
the productivity.

During a lecture on adaptive evolution, your instructor is explaining how dark-colored moths were selected for during the Industrial Revolution in England, due to their better camouflage against soot-covered trees and buildings. One of the other students in the class interrupts the lecture to insist that this example does not support the theory of evolution because the genes for both light colored and dark colored moths already existed prior to the Industrial Revolution. What mistake has your classmate made?
a. The genes for dark colored moths were in fact created by natural selection during the Industrial Revolution. b. This example is entirely hypothetical; moths do not fossilize so there is no way to document their phenotypes in the past. c. Natural selection is intended to explain the change in frequency of existing alleles in a population over time. d. Your classmate raises an original point that certainly would not be a waste of the class’s time to argue about yet again.
