What happens to the light as they go deeper in an aquatic system?

As light penetrates deeper into an aquatic system, its intensity decreases due to absorption and scattering by water molecules and suspended particles. Typically, red wavelengths are absorbed first, followed by orange, yellow, and green, with blue light penetrating the deepest. This results in a shift in the color spectrum, with deeper waters appearing more blue or green. Ultimately, below a certain depth, known as the euphotic zone, light becomes insufficient for photosynthesis.
