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? 1. Population on monarch butterflies should remain constant when milkweed population decreases.

2. Population decrease in monarch butterflies should follow population decrease in milkweed.

3. Population increase in monarch butterflies should follow population decrease in milkweed.

4. Population of milkweed should remain constant when monarch butterfly population increases
