Question

study the image and answer the questions below
food web image: phytoplankton, krill, arctic cod, ringed seal, polar bear; grass, grubs, snow goose, arctic fox; grass, lemming, arctic fox; snow goose, polar bear

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

Explanation:

To solve this, we analyze each option:

1. For the first option, there's no info suggesting a decrease in energy for Arctic Cod.
2. The second option: Arctic Fox eats Snow Goose. If goose eggs (or Snow Goose population) decrease, the energy available to Arctic Fox from this source drops, which fits energy transfer in food webs (less prey means less energy for predator).
3. The third option: Polar Bear’s food source doesn’t directly increase Arctic Fox’s energy (they have different food chains, and more Polar Bear food wouldn’t add to Arctic Fox’s energy).

Answer:

The option "There is less available energy for the arctic fox due to the decrease in goose egg availability" (exact wording may vary based on the original, but this is the correct reasoning - identify the option with this logic).

(Note: Since the original options’ exact text might have typos/partial display, the key is the logic: Arctic Fox preys on Snow Goose, so a decrease in Snow Goose (or its eggs) reduces energy for Arctic Fox. So select the option matching this explanation.)
