What are Benthos?
Organisms that live in, on, or near the bottom of a water bodies are called bethos. They includes macro-invertebrates such as worms, insects, clams, beetles, and mites. They are subdivided into two types depending on the depth of the ocean at which they are found. Benthos at the bottom of the ocean are called epifauna and those found at the greater depth are called infauna.
They can live on the substrate or inside it, and can be sessile or motile. They contribute to the energy flow within the ecosystem by participating in various ecological processes. Benthic communities are important indicator of the health of aquatic ecosystems and without these species, aquatic ecosystems would collapse.
Benthic Zone – Definition & Characteristics
The Benthic zone is the ecological region at the lowest level of a body of water such as a lake, ocean, and some sub-surface. The zone is characterized by low temperature, high pressure, and limited sunlight. The organisms that live in the benthic zone include bacteria, sea stars, and sea urchins. They play a significant role in nutrient cycling and act as a source of food for other aquatic organisms. In this article, we will learn about the benthic zone, its examples, animals, plants, and importance.
