(05.06 MC) An oil spill happened at the Wild Harbor salt marsh on Cape Cod, Massachusetts in 1969. The oil has persisted in the ground since then. How is the green crab used as evidence for the idea that oil still exists in the lower layers of the soil? (3 points)

(05.01 MC) Which scenario describes a way that an abiotic factor can impact a marine system? (3 points)

(06.04 HC) As a fishery scientist, you notice that very few cod fish have been caught in the past year. You still see very young and larval cod fish in the water, but very few adults. Explain three actions you would include in a plan for the recovery of the cod fish. Explain how you would need to address the Tragedy of the Commons to encourage those using the resource to use it appropriately. (5 points)

(06.03 MC) What is the primary benefit of continuing to use non-renewable oil, as opposed to using renewable sources of energy instead? (3 points)

(05.02 LC) Which organism could occupy the tertiary consumer trophic level in a marine food chain? (3 points)

(04.04 MC) Juvenile Red Snapper are found close to shore, while adults live and spawn in deeper water. An oil rig started seeping oil close to shore near the juvenile population of Red Snapper. What do you predict would be the biggest impact on this population due to the oil leakage? (3 points)

(05.02 MC) Why are saprotrophs so important to a marine food web? (3 points)

(04.05 LC) Which of the following is an example of overproduction in the marine environment? (3 points)

(05.03 LC) Whale lice feed off the skin of great whales and other large mammals, often causing scarring to the skin. What type of interaction is this? (3 points)

(04.01 MC) The development of some organisms, like sea turtles, are affected by the temperature at which the eggs are incubated. Typically, cooler temperatures produce more males, and warmer temperatures produce more females. How might climate change affect the reproductive success of sea turtles? (3 points)
