Would you expect there to be more energy at the level of the krill or at the level of the puffin? Explain.

It is expected at the level of the krill there is more energy.

Explanation:

In ecosystems, when one organism eats others, only a small fraction (around 10%) of energy is transferred. This implies at a higher trophic level, the energy transferred would be lower. In the case of puffins and krill, it is expected the krill feeds on organisms such as phytoplankton (algae), then organisms such as small fishes including herrings eat the krill, and bigger organisms such as puffins (birds) eat the fish.  In this context, it is expected at the level of the krill there is more energy because this is the second level, and energy has been transferred only twice.

i would go with b

cytokinesis occurs after telophase so that eliminates d

and the entire reason for cytokinesis is for cellular reproduction

affects the water bodies: excessive use of fertilizers causes eutrophication. the fertilizers which are used on plants affect the quality of land on which it is used, further causing erosion of soil. the fertilizers used on plants contain harmful chemical fumes which affect the environment.
