Question

study the image and answer the questions below

1. which statement best explains energy transfer in the above food web?

the amount of available energy for the arctic cod will decrease.
there is less available energy for the arctic fox due to the decrease in goose egg availability as of competition with polar bear
the arctic fox will have more available energy due to an additional food source for the polar bear

Explanation:

In a food - web, energy transfer follows the 10% rule where only about 10% of the energy is passed on from one trophic level to the next. Arctic cod gets energy from krill. If there is no information indicating a change in krill population, we cannot say its available energy will decrease. Polar bears do not compete with arctic foxes for goose eggs. If a new food source for polar bear appears, it will put less pressure on the other prey species in the food - web. So, the arctic fox may have more available energy as the polar bear will focus on the new food source.

Answer:

The arctic fox will have more available energy due to an additional food source for the polar bear
