Question 10

The peppered moth (Biston betularia) has two forms, a white-bodied and a dark-bodied form. The table provided shows the percentage of each type in a moth population over several years.

(See Attached Table)

The data provided on the shift in population of the peppered moth could support a claim that this population is responding to a change in the environment. In order for this data to support that claim, what other data would be needed?

Accepted Answer

Data showing a steady change in the color of trees in this habitat between 1965 and 1985.

Answer

Data showing that eventually there were no more dark-bodied moths after 1985.

Answer

Data showing that in the years after 1985 the trend reversed leading to more dark moths.

Answer

Data showing that, in 1965, the two forms migrated from different habitats.

Question 11

Information on brown tree snakes is provided along with information on the island of Guam. Brown tree snakes were first brought to Guam in 1950.

(See Attached Diagram)

Which of the following would provide evidence that the change to this environment brought about by the introduction of the brown tree snake has had an effect on the populations of organisms that lived on Guam?

Accepted Answer

The population of lizards on Guam in 1960 was very small.

Answer

Many of the military bases on Guam were closed in the 1980s.

Answer

Several other species of snakes were known to live on Guam before 1950.

Answer

The longest brown tree snake ever found on Guam measured 3 meters in length.

Question 12

A physical disruption to an ecosystem occurred when a highway was built through a forest. Which of the following would provide evidence that the addition of a highway to this forest affected populations?

Accepted Answer

There were fewer species of nesting birds living in the forest after the highway was built.

Answer

The amount of water runoff from higher elevations increased after the highway was built.

Answer

The trees that were not cut down during the construction of the highway continued to grow.

Answer

A greater area of the forest floor was exposed to the sunlight after the highway was built.

Question 13

Trout is a fish that lays its eggs in cold fresh water but spends some of its life in the ocean. Trout eat smaller fish. The graph provided shows the population of trout in the state of Wisconsin between the years 1999 and 2014.

(See Attached Graph)

Which change to the ecosystem had the largest effect on the the population of trout in Wisconsin?

Accepted Answer

The slow rise in lake temperatures in Wisconsin between 1999 and 2014

Answer

A hard freeze of many of the lakes in Wisconsin in the winter of 2006

Answer

The rise in population of smaller fish in Wisconsin lakes between 2010 and 2011

Answer

A shift in ocean currents that occurred in 2000 and again in 2001
