Distinguish between biota of the pelagic and Benthic zones of the oceans with examples
Answers
Answer: Benthic : Referring to the sea, benthic zone start at the shoreline and extends into deep waters, away from landmass. It is to be noticed that there isn’t a specified depth to this zone, as it could vary from few inches as in a stream to several 1000's of meters as in the open ocean.
Since light cannot penetrate this depth, this zone lacks the ability to photosynthesis as its energy source.
Pelagic Zone : This zone is the uppermost layers of a water body, especially referring to the ocean, interacts directly with the atmosphere. Physical and chemical properties of this zone vary greatly because of the vastness of this area, which extends from the uppermost waters down to the deeper layers near the benthic zone of a water column.
This zone can be divided into several sub layers that extend from the top to bottom
Answer:
Benthic zones
1. Benthic zone is one of the layers of the ocean which is found at the bottom of the oceanic body.
2. Benthic zone includes the rooted submerged plants and animals. The animals like crabs, fishes, prawns, and lobsters will remain on the bottom of the oceanic layer.
3. It is to be noticed that there isn’t a specified depth to this zone, as it could vary from few inches as in a stream to several 1000's of meters as in the open ocean.
4. Since light cannot penetrate this depth, this zone lacks the ability to photosynthesis as its energy source.
Pelagic Zone
1. The pelagic zone is the layer of the ocean which is found on the surface of the oceanic body.
2. In Pelagic zone plants in the form of rooted microalgae. This includes the phyto and zooplankton. The mackerel, sardine, tuna are the commonly found fish species in the zone.
3. Physical and chemical properties of this zone vary greatly because of the vastness of this area, which extends from the uppermost waters down to the deeper layers near the benthic zone of a water column.
4. This zone can be divided into several sub layers that extend from the top to bottom
