What are the categories of plankton?

What are the categories of plankton?

There are two main types of plankton: phytoplankton, which are plants, and zooplankton, which are animals. Zooplankton and other small marine creatures eat phytoplankton and then become food for fish, crustaceans, and other larger species.

What is benthos nekton and plankton?

Aquatic organisms can be divided into three groups based on where they occur in underwater ecosystems. Nekton describes animals that can swim against water currents, while plankton are plants or animals that drift in the current. Benthic organism spend their time either under, on or near the surface of the ocean floor.

What is plankton nekton benthos?

Phytoplankton and zooplankton are two types of plankton. Nekton are aquatic animals that can move on their own by swimming through the water. Benthos are aquatic organisms that crawl in sediments at the bottom of a body of water.

What’s the difference between nekton plankton and benthos?

What is the difference between Nekton Plankton and Benthos? Nekton live throughout the water column whereas plankton live closer to the water surface. Unlike nekton and planktons, benthos linked to the ocean floor. Many planktons are microscopic or small animals, when compared to the other two types.

What does plankton stand for in the ocean?

The term “Plankton” represents all the organisms that drift with ocean currents: algae (phytoplankton), animals (zooplankton). They are numerous and very abundant in the marine fauna and they represent the majority of Earth’s biomass. They cannot swim against current, but they can move vertically within the water column.

What kind of nekton live in the ocean?

Micronekton, the emphasis of this article, are small nekton, mainly fishes, squids, and shrimps. They inhabit all oceans and all depths. Many undertake diel vertical migrations into near-surface waters as light intensity decreases at dusk and then descend into deeper water before dawn.

Which is an example of a vertebrate living in the water column?

Examples include vertebrates such as fish, whales, turtles, sharks and invertebrates include squads. Nekton live throughout the water column and can move faster than water currents. Nekton propel in the water column freely either by swimming or other means.
