Mercury Concentration
Mercury is a toxic chemical that accumulates in the tissues of animals in a food chain. The chart below shows mercury levels found in various commercial fish and shellfish.
Which statement is best supported by the data in the chart?

Tilefish are the most nutritious of all the species listed.

Spiny lobsters may have more or less mercury than indicated because only a few were sampled.

Any fish caught in the Gulf of Mexico would have low levels of mercury.

Eating catfish or haddock would be most likely to cause deadly mercury poisoning.

The graph indicates that the energy used in photosynthesis is least likely obtained from which regions of the spectrum?

The yellow, orange and red regions

The violet, blue and green regions

The green and yellow regions

A small community that is heavily infested with mosquitoes was sprayed weekly with the insecticide DDT for several months. Daily counts providing information on mosquito population size are represented in the graph.
What is the most probably reason for the decreased effectiveness of the insecticide, DDT, on the mosquito population?

DDT caused lethal mutations

DDT was only sprayed once in the community

DDT chemically reacted with the DNA in the mosquitoe

Mosquitoes resistant to DDT lived and produced offspring
