Question

what causes the moose population to decrease? choose all that apply
a increased wolf population
b harsh winters
c early spring green - up
d low numbers of parasites
what happens to the wolf population when the moose population decreases?
a the wolf population increases because there is more competition for food
b the wolf population decreases because there is more competition for food
c the wolf population increases because there is less competition for food
d the wolf population decreases because there is less competition for food

Explanation:

• For the first question:
• An increased wolf population (a) would lead to more predation on moose, decreasing their numbers.
• Harsh winters (b) can make it difficult for moose to find food and survive, reducing their population.
• Early spring green - up (c) is actually beneficial as it provides more food, so it does not cause a decrease.
• Low numbers of parasites (d) mean less negative impact on moose health, so it does not cause a decrease.
• For the second question:
• When the moose population decreases, wolves have less food. More competition for the remaining food (as there are still wolves) will lead to a decrease in the wolf population.

Answer:

First question: A. Increased wolf population, B. Harsh winters
Second question: B. The wolf population decreases because there is more competition for food
