Benthic Zone

Benthic Zone

Benthic Zone Characteristics of the Benthic Zone: •Mollusks and Crustaceans: Many species of mollusks and crustaceans are found at the lake bottom, which are important for biogeochemical processes. These organisms play an important role in water filtration. •Bacteria: Due to the low oxygen levels in the deeper areas, bacterial processes in the benthic zone play an important role in the decomposition of organic matter. •Fish: Some fish species also feed on benthic organisms or use them as food during their life cycle.
