Unlike life at the top of a body of water life at the bottom of the body of water?

Life at the bottom of a body of water, known as the benthic zone, is often characterized by darker, colder, and more stable conditions compared to the surface. Organisms here, such as benthic invertebrates and certain fish species, have adapted to high pressure and low light, relying on detritus and organic matter that sinks from above for nourishment. The ecosystem is rich in unique species and plays a crucial role in nutrient cycling, contrasting with the more dynamic and diverse life found at the surface.
