Question

2.

Answer 1

Answer:

depth of light penetration

Explanation:

light is important in marine habitat, the distribution of organism, density and the type of organism is determined by the depth of light, the energy and how well the light can travel because most of the organism depends on light.

Green Plants, some algae and cyanobacteria survive through the production of their own food via photosynthesis. Photosynthate produced through photosynthesis is what is transported from area of production to other plant part where it is needed.

Photosynthesis can not be achieved without light penetration because light is what supplies the energy needed for the reaction.
