(03.02 MC) A marine biologist measured the amount of heat radiated from an aquarium over the course of an experiment. He concludes that the aquarium is an open system. Explain why this conclusion is invalid. (3 points)

(03.02 MC) A marine scientist measures the energy found in a system consisting of seagrass and sunlight. After the seagrass grows for one week, the marine scientist concluded that radiant energy from the sunlight was transformed to chemical energy in the seagrass. Does this result validate or invalidate the Law of Conservation of Energy? (3 points)

(03.03 LC) Why does the ocean appear blue in color? (3 points)

(03.06 LC) The pattern of low and high tides changes the daily habitat for organisms living in intertidal zones. Which condition, specific to the intertidal zone, is especially detrimental to organisms not adapted to low tide? (3 points)

(03.02 MC) A marine scientist measures the energy found in a system consisting of a shark and fish. After the shark consumes the fish, the marine scientist concluded that chemical energy from the fish was transformed to kinetic energy in the shark. Does this result validate or invalidate the Law of Conservation of Energy? (3 points)

(02.03 MC) As sea levels rise, which of the following will affect marine biodiversity? (3 points)

(03.01 MC) Cod grow and reproduce best when the temperature is below 54 degrees Fahrenheit. The following graph shows the temperature anomalies from 1960 to 2015. Temperature anomaly refers to the way in which the temperature is different from the long-term average. If the anomaly is negative, that means the temperature is lower than normal; if the temperature anomaly is positive, the temperature is warmer than normal. © 2016 NEAQ.org According to the graph, what prediction can be made regarding the ecosystem in which cod live? (3 points)

(03.06 MC) Which statement best describes how varying conditions in coastal areas affect the abundance of aquatic organisms living there? (3 points)

(02.06 MC) A healthy environment depends on biogeochemical cycles maintaining a balance of input and output. When forests are cut down, which process of the carbon cycle is most affected? (3 points)

(03.05 MC) How would a tsunami most likely affect the abundance of aquatic organisms in the intertidal zone of the ocean? (3 points)
