Answer 4

Thanks !(:

Answer 5

The correct answer is A.

In some places, like near a major river outlet, the salinity of water near the shore is *slightly* lower than the salinity in the deep ocean. Not much, slightly. It is well within the tolerances of the animals which have become adapted to live there.

Whereas lack of sunlight puts a strict limit on the amount of photosynthesis which can occur in the deep ocean (pretty much none can), so without much primary production, not much energy at all is available to consumers in that environment.
