Characteristics of Benthic Zone
The characteristics of the benthic zone are as follows:
- Temperature: It is warmer near the shore but as we go deep the temperature in the benthic zone varies from 2–3°C.
- Low sunlight: Lack of light is the main limiting factor and only a small amount of sunlight reaches the benthic zone.
- Pressure: The pressure in the zone is very high. It is around 1,000 times the pressure at sea level.
- Organisms: The organism present in the benthic zone are called benthos and include microorganisms, and invertebrates like sea stars, sea urchins, etc.
- Adaptations to Low Light: Penetration of light in the zone is limited and the organisms have developed various type of adaptations, such as bioluminescence to live in such conditions.
- Sediment: In the benthic zone, the sediments varies in composition from fine particles to coarse materials like gravel. It help in the recycling of the nutrients.
- Biotic Interactions: In the benthic zone, various ecological interactions takes place like predation, competition, and symbiotic relationships.
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.
