You are studying the competitive interactions between largemouth bass and lake trout in a several lakes. Some lakes have both largemouth bass and trout, while other lakes don’t have largemouth bass. You examined the gut content of a large sample of bass and trout. In lakes in which both species are found, 100% of the bass diet is composed of small fish while only 15% of the trout’s diet is composed of small fish. The remaining 85% of the trout diet’s is composed of zooplankton. In the lakes without bass, the diet of the lake trout is composed at 85% of small fish and 15% of zooplankton. What can you conclude from these results? Select one: a. Largemouth Bass will eventually completely exclude Lake Trout from the Lake. b. The absence of Largemouth Bass results in a trophic cascade. c. Largemouth Bass have a greater carrying capacity than Lake Trout. d. Without Largemouth Bass, the trout populations grow exponentially. e. The presence of Largemouth Bass prevents the Lake Trout to fulfill its fundamental feeding niche.
