Question
Chapter 21, Problem 2CT
Summary Introduction
To explain: The reason why a lack of silica would interfere with diatom reproduction.
Concept introduction: Diatoms are single-celled algae. They have cell walls of silica. Many of the algae are planktonic and extensive fossil deposits have been found. They are a major group of microorganisms that are found in the oceans, waterways, and soils of the world.

Dinoflagellates are unicellular, marine protists. Dinoflagellates are bioluminescent, but only at night. During the day, they carry out photosynthesis similar to other autotrophs. At night, however, they bioluminesce every time they are disturbed. They are often seen in the wakes of ships at night. While the reason for this bioluminescence is not fully understood, many scientists concur that it is a form of self-defense. If small fish begin to feed upon the protists, the protists will begin to bioluminesce. These flashes of light in the dark water can alert larger fish and draw them towards the small fish, upon which they prey. By making the small fish vulnerable, the dinoflagellates are able to protect themselves.
Based on the information above, a researcher decides to design an experiment in which she is testing how long it takes for dinoflagellates to recover after different amounts of disturbance. She maintains 10 containers of dinoflagellates with similar temperature, salinity and…
