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?

Answer 1

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.

Step-by-step explanation:

Answer 2

This is because benthic zone are too dark to support photosynthesis. Due to their depths, sunlight is unable to penetrate the above lying waters and reach the region. This way plants cannot carry out photosynthesis hence cannot grow. This is why only decomposers, detritus feeders can be found in the benthic zone.
