Most of the plankton in the ocean are plants. Phytoplankton produce their own food by lassoing the energy of the sun in a process called photosynthesis. So for sunlight to reach them, they need to be near the top layer of the ocean.

Where are most planktonic organisms found?

They are mostly found in the sunlit zone of the water column, less than 200 metres deep, which is sometimes called the epipelagic or photic zone. Ichthyoplankton are planktonic, meaning they cannot swim effectively under their own power, but must drift with the ocean currents.

Where does plankton live?

Plankton can be found in saltwater and freshwater. One way to tell if a body of water has a large plankton population is to look at its clarity. Very clear water usually has less plankton than water that is more green or brown in color.

What are planktonic organisms?

The word “plankton” comes from the Greek for “drifter” or “wanderer.” An organism is considered plankton if it is carried by tides and currents, and cannot swim well enough to move against these forces. ... But the most basic categories divide plankton into two groups: phytoplankton (plants) and zooplankton (animals).

Where are plankton algae found?

Phytoplankton, both algae and cyanobacteria, can be found in fresh or saltwater 13. As they need light to photosynthesize, phytoplankton in any environment will float near the top of the water, where sunlight reaches 10.

Which plankton is smallest?

Cyanobacteria - The smallest plankton (< 0.2 µm) blue-green algae are abundant in the oceans and sometimes in freshwater. Their outer membrane is very hard to digest; not many larger plankton eat them until that membrane is destroyed by a few species of bacteria and virus.

Who eats phytoplankton?

Phytoplankton and algae form the bases of aquatic food webs. They are eaten by primary consumers like zooplankton, small fish, and crustaceans. Primary consumers are in turn eaten by fish, small sharks, corals, and baleen whales.

Are phytoplankton bacteria?

What produces 70% of Earth's oxygen?

Prochlorococcus and other ocean phytoplankton are responsible for 70 percent of Earth's oxygen production.

Is a jellyfish a plankton?

Jellyfish are plankton—they're drifters. Usually we think of plankton as being tiny, and many of them are, but plankton just means living things in the water that can't fight a current, which includes floating jellies. That drifting is an important consideration when designing their habitats!

Is plankton poisonous?

Most phytoplankton are harmless to animals. However, a few species can produce toxic, or poisonous, chemicals. Some dinoflagellates and diatoms can make poisonous compounds that cause diarrhea, paralysis, dizziness, and even memory loss. Yikes!

Is a fish a decomposer?

The food-chain includes the producer, primary consumer, secondary consumer and decomposers.

Is sunfish a plankton?

All jellyfish, and the Ocean sunfish are such feeble swimmers that they too are included as plankton. Most of the plankton in the ocean are plants. Phytoplankton produce their own food by lassoing the energy of the sun in a process called photosynthesis.

Can humans see plankton?

Even though they may be ten to 100 times larger than a bacterial cell, you would still need to look through a microscope to see these organisms. Some plankton are big enough to be seen with the naked eye.

What causes a phytoplankton bloom?

More generally, a bloom can be considered as a phytoplankton population explosion-blooms occur when sunlight and nutrients are readily available to the plants, and they grow and reproduce to a point where they are so dense that their presence changes the color of the water in which they live.
