For a lake in Michigan, researchers have determined that largemouth bass feed on smaller fish, which in turn feed on zooplankton. In 2016, there was 600,000 kg of zooplankton in the lake. In 2017, an accidental runoff of insecticide near the lake caused a 50 percent decline of the zooplankton population in the lake. Assuming 10 percent trophic efficiencies, what is the expected decline in largemouth bass?
(a) 1,000 mg.
(b) 1,500 kg.
(c) 2,000 kg.
(d) 3,000 kg.
