Krill in this food web is the primary consumer. Since the producer of the food web is the phytoplankton. Removing them from the food chain cuts the supply of food for secondary consumers such as seals, and whales. This disrupts the whole Antartic ecosystem since there will be a large amount of phytoplankton but not enough food for secondary consumers. This because secondary consumers are not able to eat phytoplankton due to their microscopic size. Only krill are able to feed on them and have the maximum energy gain from them.

Pretend that you are writing a letter to the president proposing ways that the US can reduce its contribution to climate change.
ahrayia [7]

Answer:

Dear Mr. President,

Your strong voice has called attention to the risks of human-induced climate change and the need to take timely and effective steps to address it. We are pleased to report further progress in our efforts to advise you on climate policy options that could help encourage these steps.

Mr. President, our temperatures are consistently rising while moisture is increasingly evaporating. Forest management is merely one piece of the puzzle — something our own firefighters would be quick to remind you. Since 2009, our state has spent more than $130 million on forest health and fire preparedness. These events still overwhelm our residents and resources, because these fires are unlike anything people have seen before.

Sincerely,

Explanation:

hope this helps!
