Why is an herbivore considered a predator.

• An herbivore’s prey is a plant and plants are organisms.

• An herbivore's prey are rocks.

What is an example of how predators affect prey populations?

• The squirrels in a tree eat nuts.

How does the scarcity of prey populations affect predator populations?

• Too many predators means the prey population will increase (go up)

• Scarcity (not enough) of a prey population leads to a decrease in the predator population.

What describes mutualism?

• Two species that harm each other

• Two species rely on each other to survive

How might a decrease in the population of one species likely affect the other species in a mutualism?

• A decrease in population of one species will likely cause a decrease in the other population.

• A decrease in population of one species will likely cause an increase in the other population.
