As you saw in Section 2 ("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 Iake 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. Decornposition decreases, dissolved oxygen increases and fish populations grow
b. Decomposition increases, dissolved oxygen decreases , and fish populalions die off
c. Decomposition increases, dissolved oxygen decreases , and fish populations grow
d. Decomposition increases, dissolved oxygen increases and fish populations die off
