When warming temperatures gradually melt sea ice over time, fewer bright surfaces are available to reflect sunlight back into the atmosphere. More solar energy is absorbed at the surface and ocean temperatures rise. This begins a cycle of warming and melting.
Answer:
Explanation:
1)It is better to stick to the lower trophic levels around 2 because it is more consumable.
At the lowest trophic level, there is the lowest consumption of energy. As a result, more people can be fed with the lower trophic levels than the higher trophic levels.
Edit: Sorry forgot to do question 2
2) Different levels in a food web...
<span>Water has a surface skin. Some insects are able to generate tiny bubbles under their bodies which makes them buoyant enough to not break thru the water's skin. This skin is also known as surface tension. </span><span>Some bugs and small objects (pins or paperclips, etc) can rest on the surface of the water due to surface tension. Water molecules are bipolar and attract each other forming a skin. The bug or paperclip make tiny depressions in the water skin which provides buoyancy. A detergent will ruin the water tension (because it is a wetting agent) and the bug or paperclip will sink.</span><span>

The answer D sorry if I’m wrong
