Question
Chapter 39, Problem 12WIO
Summary Introduction
To explain:
Why not the phytoplankton maintains deep water oxygen level in eutrophic lake.
Concept introduction:
The eutrophic lake has a higher number of productivity because the nutrient content in eutrophic lake is high. This support the growth of algae and other aquatic plant. The growth of algae start consuming oxygen, which result in oxygen depletion in a eutrophic lake.
