Question

Which environmental factor controls the amount sunlight that reaches underwater plants and animals?

Answer 1

The environmental factor that controls the amount sunlight that reaches underwater plants and animals would be the abiotic factors. As with terrestrial biomes, aquatic biomes are influenced by a series of abiotic factors.

Answer 2

The abiotic factor is the right answer.

Abiotic factors are the factors that affect aquatic biomes including light availability, stratification, depth, temperature, tides and currents. A series of abiotic factors affect the aquatic biomes just like the terrestrial biomes. Nevertheless, these factors vary since water has unconventional physical and bio-chemical characteristics than does wind.
