Question 1

The graph below shows information about the growth of a population.

Which best explains what occurred at point X on the curve?

The birth rate was equal to the death rate.

The death rate was greater than the birth rate.

The rate of emigration was equal to the birth rate.

The rate of immigration was greater than the death rate.

Question 2

Disease killed off species 1 beginning in May

the food sources for species 1 increased while the food sources for species 2 decreased from January through November.

Mutations occurred from April through September in both species, resulting in both species becoming better adapted to the environment.

The weather was hotter and dryer than normal from April through September.

Question 3

Native ant species preyed on the Red Imported Fire Ant and increased in population.

Native ant species interbred with the Red Imported Fire Ant, creating new ant species.

The Red Imported Fire Ant caused native ant species to become more susceptible to predators.

The Red Imported Fire Ant caused a decline in native ant species by competing for their resources.

Question 4

It will increase as polar bears adapt to other habitats.

It will increase because polar bears will have fewer predators.

It will decrease as the habitat suitable for polar bears decreases.

It will decrease because polar bears will become easier to hunt.
