Where would you expect to find the largest concentration of mercury within marine life?Question 9Answersea birdsbenthic organismssharksshrimp

During gold mining activities along the Amazon River, mercury (which is used to separate gold from other minerals) is released and dissolves in the water. Which organism would have the highest concentration of mercury in its tissues? A.A bird that feeds on large fish that swim in the riverB.A large fish that feeds on smaller fish in the riverC.A small fish that feeds mostly on algae growing in the riverD.Soybeans watered with water from the river

As a result of biomagnification, mercury levels would be highest in a(n)Multiple choice question.herbivore.tertiary consumer.primary consumer.producers.

A population of otters (tertiary consumers) lives in an ecosystem in which mercury is at a concentration of 0.004 g/kg in primary producers. What is the approximate concentration of mercury in otters? Assume that 90% of the energy at each trophic level is lost as heat, and that no mercury is excreted or breaks down through the food web.Multiple Choice0.04 g/kg4 g/kg0.4 g/kg0.0004 g/kg

When is mercury a concern for human health?Question 4Answerwhen people swim at the beachwhen ships sail into the Pacific gyrewhen oysters  filter feed in Boston Harborwhen people eat canned tuna

The FDA regulates that a fish that is consumed is allowed to contain at most 1 mg/kg of mercury. In Florida, bass fish were collected in a random sample of different lakes to measure the average amount of mercury in the sample of fish from each lake. The data for the average amount of mercury in each lake is in table below. Do the data provide enough evidence to show that the fish in all Florida lakes have a lower mercury level than the allowable amount?
