Beaked whales feed at various depths, but they defecate at the ocean’s surface. Nitrogen-rich whale feces deposited in surface waters supply nutrients for algae that are eaten by surface-dwelling fish. Which of the following best predicts what would happen if the whale population decreased?
29There would be a reduction in surface nitrogen concentration, which would cause an algal bloom.
The remaining whales would accumulate mutations at a faster rate.
The surface fish populations would decline due to reduced populations of algae.
The remaining whales would be forced to foragein the deepest parts of the ocean.

300s - Q6
Although extinction is a natural process, current extinctions are of concern to environmentalists because
most current extinctions are caused by introduced species
the rate of extinction is unusually high.
None of these answers is correct
current extinction is primarily affecting plant diversity

Carbon dioxide and other gases prevent some heat from escaping Earth's atmosphere. This is known as the ____ effect.
warming
summer
carbon dioxide
greenhouse
300s - Q8
Undersea landslides can disrupt marine habitats by burying organisms that live on the ocean floor. The graph above shows the size of a population of a certain organism that lives on the ocean floor. The population was affected by a recent landslide at the time indicated on the graph. Which of the following best predicts how the population will be affected by the landslide?
The reduced population will likely have allelic frequencies that are different from the initial population
The population will adapt to deeper waters to avoidfuture landslides
The reduced population will have a greater number ofdifferent genes than the initial population
The surviving organisms will evolve into a new species
300s - Q9
The symbiotic relationship between a flower and the insect that feeds on its nectar is an example of
predation because the insect feeds on the flower
commensalism because the insect does not harm the flower and the flower does not benefit from the relationship
parasitism because the insect lives off the nectar from the flower
mutualism because the flower provides the insect with food, and the insect pollinates the flower.
