The Benthic Zone is the lowest layer of a body of water, such as oceans, lakes, and rivers. It includes the sediment surface and sub-surface layers, where organisms like worms, clams, and various types of bacteria live. This zone is crucial for the ecosystem, as it serves as a habitat for many species and plays a role in nutrient cycling. In the Benthic Zone, organisms are often adapted to high pressure and low light conditions. Some creatures, like sea cucumbers and starfish, help break down organic matter, while others, like benthic fish, rely on this zone for food. Overall, the Benthic Zone is vital for maintaining the health of aquatic environments.
