Question

A lake has very deep water at the bottom, in the benthic zone. why is it more difficult for plants to live in the benthic zone of this lake than in the littoral zone? apex

Answer 1

It is more difficult for plants to live in the benthic zone of the lake than in the littoral zone because the benthic zone lacks ample availability of dissolved oxygen and sunlight.

Step-by-step explanation:

• The benthic zone forms the part of the floor of the lake. If the lake is very deep, it is clear that the sunlight must not be reaching the benthic zone of the lake.

• Also, the concentration of dissolved oxygen there would also be comparatively less than the littoral zone which is in adjacency with the atmosphere and is thus supplied with ample oxygen.

Answer 2

The benthic zone is the ecological region at the lowest level of a body of water such as an ocean or a lake.
It is more difficult for plants to live in the benthic zone of this lake, which has very deep water at the bottom, than in the littoral zone because light does not penetrate very well to such depths. And plants need light in order to survive.
