(04.04 MC) Which of the following is an r-selected species in the ocean and why? (3 points)

(06.04 MC) Using the graph below, what can you infer about the correlation of U.S. crude oil production and imports between 1920 and 2020? (3 points) © 2016 CC-BY-SA

(06.01 LC) What do scientists call a non-native species that reproduces quickly and spreads in an environment when these organisms can cause harm to an ecosystem? (3 points)

(04.05 HC) The Atlantic puffin feeds on several different species of Atlantic fish. A population of puffins living on Matinucus Rock was found to feed primarily on the types of fish shown in the graph below. The beaks of this group of puffins are shaped to grasp species A particularly well because it is the main species of fish in the ocean around this island. Suppose a puffin in this population is born with a shorter beak that cannot effectively grasp Species A. Predict what would happen to this bird. Explain your reasoning based on what you know regarding genetic adaptations. (3 points)

(04.05 MC) In the Galapagos islands, larger iguanas are more successful at reproducing and have more offspring. How would the population change if larger body size also makes iguanas more vulnerable to predatory birds? (3 points)

(06.04 HC) In one fishing ground off the coast of England, herring were fished so extensively that their numbers dropped 30-fold in 15 years. A fishing ban allowed herring numbers to rebound to the extent that they are now a species of least concern. For a species that is declining, like the herring, why might a scientists want to establish a “no-fishing” zone (like a marine protected area) as a tool for dealing with overfishing? Explain two benefits and list at least one potential limitation of this type of intervention. (5 points)

(06.01 MC) Why does the presence of invasive species generally result in a decrease in biodiversity of native species in an area? (3 points)

(06.04 LC) What can you logically infer from the following facts: (3 points) There is a greenhouse effect Carbon dioxide is a greenhouse gas People have increased the concentration of carbon dioxide in the atmosphere dramatically since industrial times

(06.03 LC) What is the most effective long-term solution to reduce the amount of carbon dioxide emissions? (3 points)

(06.03 LC) Is oil a renewable or nonrenewable resource? Why? (3 points)
