Question

Why are green algae not likely to be found in the deepest strata of the ocean?​

Answer 1

Here's the Answer

Green algae survive by utilisation of food synthesised by themselves through photosynthesis. At deepest layer in ocean, light is absent. So, photosynthesis does not take place and hence, green algae are not found in deep strata.

Answer 2

Green algae are not found beyond a certain depth in ocean because only about 1 percent of sunlight penetrates at this depth which is not sufficient for the plants to photosynthesize and thus grow, and survive.
