D) light quality.
E) salinity.

Question

Quizplus · Accepted Answer

The depth distribution of algae is limited by light quality. Algae require sunlight for photosynthesis, so their distribution is limited by the availability and quality of light penetrating the water column. As depth increases, the amount of light available for photosynthesis decreases, and certain wavelengths of light are absorbed more readily than others, which further limits the depth distribution of specific types of algae.
