The best explanation for the decline in the mouse population is option B.
Explicación
## Step 1The problem presents a situation where the hawk population in a grassland ecosystem is declining due to a disease caused by a poxvirus. The question asks us to explain why the mouse population is also experiencing a decline.## Step 2We need to analyze each option and determine which one best explains the decline in the mouse population.## Step 3Option A suggests that the remaining hawks are eating only mice. However, this doesn't explain why the mouse population is declining. If the hawks were eating only mice, the mouse population would likely increase, not decrease.## Step 4Option B suggests that the snakes are increasing with fewer predators feeding on them. This could lead to an increase in the snake population, which could then prey on the mice, leading to a decline in the mouse population.## Step 5Option C suggests that the grasshoppers are beginning to feed on the mice too. However, grasshoppers are not known to prey on mice, so this option is unlikely.## Step 6Option D suggests that there is an abundance of grass. This doesn't explain why the mouse population is declining. In fact, an abundance of grass could provide more food for the mice, leading to an increase in their population.
