What zone does phytoplankton live in?

photic zone
Phytoplankton live in the photic zone of the ocean, where photosynthesis is possible. During photosynthesis, they assimilate carbon dioxide and release oxygen.

Which Zone has the highest distribution of photosynthetic organisms?

Ninety percent of marine life lives in the photic zone, which is approximately two hundred meters deep. This includes phytoplankton (plants), including dinoflagellates, diatoms, cyanobacteria, coccolithophorids, and cryptomonads.

Do all Nektonic organisms live in the photic zone?

Nekton. Nekton are the largest and the most obvious animals in the photic zone, but also the least abundant. These are the fishes, marine mammals, worms, sponges, molluscs, sea stars and reptiles. While some of these large animals feed on fish, others, such as the baleen whale, feed on plankton.

What zone do zooplankton live in?

euphotic zone
Zooplankton’s Place in the Food Web Many species of zooplankton live in the euphotic zone of the ocean—the depths at which sunlight can penetrate—feeding on phytoplankton.

Which zone gets the most sunlight for the photosynthesis?

Let the Sun Shine In Lots of marine animals can be found in the sunlit zone including sharks, tuna, mackerel, jellyfish, sea turtles, seals and sea lions and stingrays. There are not a lot of places to hide in the sunlit zone! Some species have an adaptation called countershading.

What are some factors that affect aquatic biomes?

Abiotic factors that influence aquatic biomes include light availability, depth, stratification, temperature, currents, and tides.

What are Nektonic organisms?

Nekton (or swimmers) are living organisms that are able to swim and move independently of currents. Nekton are heterotrophic and have a large size range, with familiar examples such as fish, squid, octopus, sharks, and marine mammals.

What are two important adaptations to life in the Disphotic zone?

The animals that live in the disphotic zone are adapted to life in near darkness, cold water and high pressure. Many of the animals in this zone have large eyes, helping them see in the nearly dark waters. Most are small, dark and thin (to help camouflage them). Many have large teeth and jaws.

What is the temperature of the photic zone?

On average, it extends to about 660 feet (200 meters); the depth of the ocean averages about 13,000 feet or 4,000 m. The temperature in this zone ranges from 104 to 27 degrees F.
