The milkweed plant serves an 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 monarchs
and milkweed, which of the following trends would be predicted
when looking at data on the populations of these two
organisms?
A
Population decrease in monarch butterflies should
follow population decrease in milkweed.
B
Population of monarch butterflies should remain
constant when milkweed population decreases.
с
Population increase in monarch butterflies should
follow population decrease in milkweed.
D
Population of milkweed should remain constant when
monarch butterfly population increases.
