The lavender plant serves an important role in the life cycle of the monarch butterfly. Adult monarchs lay their eggs in the lavender plant, and then the monarch caterpillars eat that same plant during their development.

Based on the relationship between monarchs and lavender, what is one reasonable prediction a scientist could make?

• If the lavender population goes down, the monarch population will do down.

• Population of monarch butterflies should remain constant when lavender population decreases.

• A decrease in the lavender population would cause a monarch butterfly population increase.

• If the population of lavender remains constant (the same), the monarch butterfly population increases.

Due to limited resources, what may happen to the buffalo in this picture?

• one would become a predator and eat the other buffalo

• there would be mutualism and they would work together to find more water

• they would find something else to prey upon and get water from the prey

• competition would result in some getting enough water and others not getting enough water
