Available food resources.
Population of the species.
Annual rainfall.

Bighorn sheep hibernate during the winter while mountain goats remain active.
Erosion in the habitat affects the both animals ability to safely raise their young and decreases their populations.
Both bighorn sheep and mountain goats feed on the same grasses.
Laws prevent human from being able to hunt bighorn sheep or mountain goats.

Wolves, which prey on deer, were being hunted more than usual.
Rainfall in the previous spring was higher than the yearly average.
Humans introduced grazing animals that feed on the same plants as the deer.
More insects that pollinate flowering plants move into the habitat.

What data would be most helpful to support the claim that the population of a certain plant is dependent on the rainfall in its habitat.
The average amount of water absorbed by the roots and given off by the leaves of these plants.
The amount of water retained in the soil in the area where the plants live.
Rainfall amounts and number of these plants in a certain habitat over several years.
The heights and number of leaves produced by these plants under different moisture conditions.
The milkweed plant serves and important role in the life cycle of the monarch butterfly. Adult monarchs lay their eggs in milkweed, and then caterpillars eat that same plant during their development. Based on the relationship between the monarchs and milkweed, which of the following trends would be predicted when looking at data on the populations of these two organisms?
Population decrease in monarch butterflies should follow population decrease in milkweed.
Population of monarch butterflies should remain constant when milkweed population decreases.
Population increase in monarch butterflies should follow population decrease in milkweed.
Population of milkweed should remain constant when monarch butterfly population increases.

In a forest habitat, select the correct description of the relationship between rabbits and foxes.
Rabbits are competitive with Foxes
Foxes are competitive with Rabbits
Rabbits are dependent on Foxes.
Foxes are dependent on Rabbits.
Select the best explanation as to why the wolf population decreased dramatically in the graph.
Bears were introduced, which provided competition to the wolves.
The moose began hunting the wolves.
The moose are competitive with the wolves, and began dominating the same resources.
The wolves are dependent on the moose, so when the moose population decreased there wasn't enough food to support the large wolf population.
