As you saw in "DO or Die", adding nutrients to a lake has direct effects (such as stimulating the growth of phytoplankton) and indirect effects throughout the community (such as drastic effects on fish populations). Suppose you triple (3x) the phosphorus input in a lake where phosphorus is limiting, and phytoplankton populations grow dramatically. Based on your observations, which of the following predictions is most likely to follow the phytoplankton bloom? a. Decomposition decreases, DO increases, fish populations grow, and zooplankton abundance increases. b. Decomposition increases, DO decreases, fish populations die off, and zooplankton abundance increases. c. Decomposition increases, DO decreases, fish populations grow, and zooplankton abundance decreases. d. Decomposition increases, DO increases, fish populations die off, and zooplankton abundance decreases.
