Difference Between Pelagic and Benthic zone
The differences between Pelagic and Benthic zone are as follows:
Feature | Pelagic Zone | Benthic Zone |
---|---|---|
Location | Open water column away from the bottom | Bottom of the water body |
Depth | Surface water (epipelagic), midwater, deep-sea | Varies from shallow coastal areas to deep ocean |
Sunlight Availability | Abundant sunlight in surface layers | Diminished sunlight, especially in deeper areas |
Temperature | Surface temperatures can vary widely | Generally cooler and more stable |
Organisms | Plankton, nekton (fish, whales), some jellyfish | Benthic organisms such as algae, invertebrates, and bottom-dwelling fish |
Adaptations | Adapted to water column dynamics, currents | Adapted to life on or near the ocean floor |
Food Sources | Phytoplankton, zooplankton, smaller organisms | Detritus, organic matter, smaller benthic organisms |
Examples | Open ocean, surface waters, deep-sea environments | Ocean floor, continental shelves, abyssal plains |
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.
