Question

What affect does the change in light penetration have on the plants tha grow deeper in the water

Answer 1

Plants need sunlight to live in order to generate photosynthesis, so they might have to adapt to the water, or grow much larger and get closer to the sun.

Answer 2

The intensity of light affects the plants that grow in the deeper water because they already lack sunlight in deeper part of water.

The levels of light also shows the presence of green plants inside water. The more the light will penetrate deep the more will the presence of photosynthetic plants.

So, the intensity of light will determine the plants and other photosynthetic organism in water.
