Key Points
- The term "benthos" is used to describe the community of organisms that live on, in, or near the seabed, also known as the benthic zone.
- This includes both plant and animal life.
- The benthic biome is one of the critical components of the ocean's ecosystem.
- It includes seaweeds, sponges, mollusks, crabs, starfish, and many other species.
- Benthos plays a crucial role in the ocean's food chain and nutrient cycles.
Additional Information
- Plankton are small and microscopic organisms drifting or floating in the sea or freshwater. They form the base of the food chain in aquatic ecosystems.
- Necton refers to aquatic animals that can swim and move independently of water currents, including fish, squid, and marine mammals.
- Corals are marine invertebrates within the class Anthozoa of the phylum Cnidaria. They typically live in compact colonies of many identical individual polyps.
- The group includes the important reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton.
- Although corals are a vital part of the marine ecosystem, they are not synonymous with the term for plant biomes beneath the sea.
