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

Answer:the environmental factor that influences the amount of sunlight that reaches the underwater plants and animals are abiotic factors. Aquatic biomes are influenced by a series of abiotic factors. However, these factors differ since water has different physical and chemical properties than does air. Even if the water in a pond or other body of water is perfectly clear (there are no suspended particles), water, on its own, absorbs light. As one descends into a deep body of water, there will eventually be a depth which the sunlight cannot reach. While there are some abiotic and biotic factors in a terrestrial ecosystem that might obscure light (such as fog, dust, or insect swarms), usually these are not permanent features of the environment.
