Question 12
Scientists researching Pacific sea otters find that many members of the population are infected by a parasite, and a number of the sea otters must be destroyed to save the entire sea otter population. One of the main foods of sea otters is sea urchin, which eat kelp. The kelp forest is home to many species of fish. How is destroying some of the sea otters most likely to affect fish living in the kelp forest?

Emergency sea otters needed to save California's kelp forests

a
Destroying the sea otters will cause the fish population to become extinct.
b
Destroying the sea otters will cause the fish population to decrease.
c
Destroying the sea otters will allow the fish population to remain constant.
d
Destroying the sea otters will cause the fish population to increase.

Question 16
A student is investigating the effect of light intensity on the rate of photosynthesis. She observes that as light intensity increases, the rate of photosynthesis increases. Which explanation best describes how the rate of photosynthesis can affect the biodiversity of an area?

a
A high rate of photosynthesis can increase biodiversity because it allows more producer populations to survive which then attract consumer populations.
b
A low rate of photosynthesis can increase biodiversity because it allows more producer populations to survive which then deter consumer populations.
c
A high rate of photosynthesis can decrease biodiversity because it allows more producer populations to survive which then deter consumer populations.
d
A low rate of photosynthesis can increase biodiversity because it allows more producer populations to survive which then attract consumer populations.

What may cause a population to temporarily overshoot its carrying capacity?
a
a reproductive time lag
b
an increase in predators
c
a decrease in birth rates
d
