In the example of the predator/prey web in the grassland community on Bylot Island, a rise in the snowy owl population would have what effect on the snow goose?
A)The snow goose population would rise due to owls preying upon foxes.
B)The snow goose population would fall due to an increase in the fox population.
C)The snow goose population would fall due to a lower consumption of grasses.
D)The snow goose population would rise due to lemming, and subsequently fox, populations declining.
E)The snow goose population would not be affected at all.

An increase in the snowy owl population would likely lead to a decrease in the lemming population, as lemmings are a primary prey for snowy owls. With fewer lemmings, the fox population, which also preys on lemmings, might decline due to a lack of food. With fewer foxes to prey on them, the snow goose population could potentially rise. This is an example of an indirect effect in a predator/prey web.
