Three descriptions of the processes that occur during eutrophication are listed.
  1. 1
    decreased aerobic respiration by fish
  2. 2
    increased decomposition of aquatic plant protein to ammonium ions
  3. 3
    increased conversion of nitrate ions to amino acids in aquatic plants
What is the correct order of these processes during eutrophication?
