Question

how will this most likely affect the species in this ecosystem?
○a. there will be an increase in bees and mice which will cause an increase in the populations of both black bears and foxes.
○b. there will be a decrease in bees and mice which will cause an increase the black bear population and a decrease in the fox population.
○c. there will be a decrease in bees and mice which will cause a decrease in the populations of both black bears and foxes
○d. there will be an increase in bees and mice which will cause a decrease in the black bear population and an increase in the fox population.

Explanation:

If there is a decrease in plants (assuming a scenario like plant destruction not shown but implied in such questions), bees (which rely on plants for nectar etc.) and mice (which rely on plants as food source) would decrease. Black bears eat bees (indirectly via bee - related products like honey) and foxes eat mice. So, a decrease in bees and mice would lead to less food for black bears and foxes, causing a decrease in their populations.

Answer:

C. There will be a decrease in bees and mice which will cause a decrease in the populations of both black bears and foxes.
