GEOLOGY

Detailed explanation-1: -The benthic zone is the ecological region at the lowest level of a body of water such as an ocean, lake, or stream, including the sediment surface and some sub-surface layers.

Detailed explanation-2: -The benthic zone is the lowest ecological zone in a water body, and usually involves the sediments at the seafloor. These sediments play an important role in providing nutrients for the organisms that live in the benthic zone.

Detailed explanation-3: -Benthos that are found on the ocean floor are known as epifauna, while those found at greater depths are known as infauna.

Detailed explanation-4: -The Abyssal Zone is one of the many benthic zones we have highlighted to describe the deep oceans. This particular zone is found at depths of 2, 000 to 6, 000 meters (6, 560 to 19, 680 feet) and stays in perpetual darkness.

Detailed explanation-5: -Despite being out of sight, the benthic zone is a highly important contributor to lake ecosystems. This area alone offers spawning, foraging and shelter opportunities for various aquatic species. The benthic zones in the shallow shoreline waters provide ideal conditions for fish and amphibian spawning.
