QUESTION 11 A hypothetical lake contains two species of algae, two species of zooplankton that eat algae, and one species of juvenile salmon (parr) that feeds on the zooplankton: Algae 1 outcompetes algae 2 - Zooplankton 1 outcompetes zooplankton 2 - Both zooplankton prefer algae 1, but will feed on algae 2 if algae 1 is unavailable - The salmon parr prefers to prey on zooplankton 1 Given the competitive and feeding relationships listed above, which scenario is the most likely? When the salmon parr are absent, zooplankton 2 is more abundant than zooplankton 1 and algae 1 competitively excludes algae 2 completely from the community. When the salmon parr are absent, zooplankton 1 is more abundant than zooplankton 2 and total algal abundance is higher than when the parr are present. When the salmon parr are present, zooplankton 2 is more abundant than zooplankton 1 and the total algal abundance is higher than it is when the parr are absent. When the salmon parr are present, zooplankton 2 is more abundant than zooplankton 1 and algae 2 is more abundant than algae 1.

QUESTION 11 10 A hypothetical lake contains two species of algae, two species of zooplankton that eat algae, and one species of juvenile salmon (parr) that feeds on the zooplankton: Algae 1 outcompetes algae 2 Zooplankton 1 outcompetes zooplankton 2 - Both zooplankton prefer algae 1, but will feed on algae 2 if algae 1 is unavailable - The salmon parr prefers to prey on zooplankton 1 Given the competitive and feeding relationships listed above, which scenario is the most likely? When the salmon parr are absent, zooplankton 2 is more abundant than zooplankton 1 and algae 1 competitively excludes algae 2 completely from the community. When the salmon parr are absent, zooplankton 1 is more abundant than zooplankton 2 and total algal abundance is higher than when the parr are presént. When the salmon parr are present, zooplankton 2 is more abundant than zooplankton 1 and the total algal abundance is higher than it is when the parr are absent. When the salmon parr are present, zooplankton 2 is more abundant than zooplankton 1 and algae 2 is more abundant than algae 1.
