The deer were starving to death, so the deer population went up. Question 3 4. If wolves had not been introduced, would the deer population have been able to grow at the same rate forever?(1 point) Responses No, the deer population would have grown quickly for a while but eventually would have been limited somewhat by lack of food and by disease. No, the deer population would have grown quickly for a while but eventually would have been limited somewhat by lack of food and by disease. Yes, the deer population would have grown quickly forever because nothing else limits population other than predators.

Wolves are prey and the deer are predators. Wolves are prey and the deer are predators. Wolves are parasites and the deer are the hosts. Wolves are parasites and the deer are the hosts. Wolves and deer mutually help each other. Wolves and deer mutually help each other. Question 6 7. Which description correctly describes predators and prey?(1 point) Responses Predators and prey compete with each other for all of the same biotic and abiotic resources. Predators and prey compete with each other for all of the same biotic and abiotic resources. Predators hunt, kill, and eat prey. Predators hunt, kill, and eat prey. Predators live on or in the prey causing the prey harm by feeding on it continually and eventually causing the prey to die.

The deer and wolf populations changed slowly and then stabilized. The deer and wolf populations changed slowly and then stabilized. The deer and wolf populations both grew rapidly the whole time. The deer and wolf populations both grew rapidly the whole time. Question 9 10. What is the most likely explanation for the way the graph looks for the period from 2018 to 2020?(1 point) Responses The wolf and deer populations were stabilized because the number of predators and the number of prey were well balanced. The wolf and deer populations were stabilized because the number of predators and the number of prey were well balanced. The wolf and deer populations were not stabilized because all the wolves stopped eating. The wolf and deer populations were not stabilized because all the wolves stopped eating. The wolf and deer populations were stabilized because all other predators and prey died. The wolf and deer populations were stabilized because all other predators and prey died.
