What are the components of phytoplankton in marine ecosystems?

Phytoplankton, that is, planktonic algae, is the main primary producer of freshwater water bodies, and the phytoplankton community responds very quickly to environmental changes, and is a general term for several algae that live suspended in water. Phytoplankton are widely found in rivers, lakes and oceans, and are affected by natural conditions such as water flow, water temperature, nutrients, light, and biological factors such as algae death, sedimentation, aggregation, and predation, and are very sensitive to environmental changes. The abundance and dominant populations of phytoplankton can effectively reflect the impact of human activities on the ecological environment of water bodies.

Units carrying out phytoplankton detection in marine ecosystems:

The Marine Environmental Monitoring and Evaluation Laboratory of the Chinese Academy of Sciences can carry out the detection of phytoplankton in water.

Marine water bodies are mainly composed of pure water, non-algae particulate matter, phytoplankton, and colored soluble organic matter. Marine phytoplankton synthesize oxygen through photosynthesis and are an important part of natural ecosystems. Studying the distribution of phytoplankton in marine water bodies has important scientific research value for water research and ecological research.

Suspended particulate matter in water refers to all organic and inorganic particulate matter suspended in water, which is an important component of water and an important factor affecting the optical properties of water.

Plankton includes two major groups: phytoplankton and zooplankton.

Plankton can be divided into 6 groups based on their size.

Phytoplankton: Most of them are single-celled plants, of which diatoms are the most, as well as dinoflagellates, green algae, cyanobacteria, golden algae, etc.

Zooplankton: includes most of the phyla invertebrates, such as protozoa, coelenterates (all kinds of jellyfish), rotafers, crustaceans, gastropod molluscs (pteropods and heteropods), hairy jaws, lower chordates (planktonic tails and sea bottles), as well as floating eggs and planktonic larvae of various animals.

Summary. Hello, because the plants in the ocean are mostly tiny phytoplankton; There are many types of animals, most of which can swim in the water. The forest ecosystem is distributed in the humid area, there are many kinds of animals and plants, yo conserve water, maintain the role of water and soil, plants are mainly arbors, animals are mainly arboreal and climbing life, there are green phytoplankton are marine organisms.

Ok thanks.

Hello, because the plants in the ocean are mostly tiny phytoplankton; There are many types of animals, most of which can swim in the water. The forest ecosystem is distributed in the moist area of the branches, there are many kinds of animals and plants, yo collapse and sensitive water conservation, the role of maintaining water and soil, the plants are mainly arbors, the animals are mainly arboreal and climb and take the help of life, there are green phytoplankton are marine organisms.

The most abundant organisms in the sea are: algae, plankton. Phytoplankton is an ecological concept, which refers to the tiny plants that live in plankton in the water, usually phytoplankton refers to planktonic algae acres, including cyanobacteria, green algae, diatoms, goldenrods, xanthellophyta, dinoflagellates, xanthellapace, cryptophyta and euglena.

The species of life in the ocean are very different from those on land. The vast majority of the plants in the ocean are tiny planktonic plants. There are many species of animals in the ocean, from protozoa with single combustion wheels to the largest blue whale in the animal, most of which can swim in the water.

Hello, marine plankton refers to tiny organisms that float in the ocean, including phytoplankton and zooplankton seepping fingers. Here are some common marine plankton:

1.Phytoplankton, such as diatoms, calcareous algae, dinoflagellates, etc., are the most important primary producers of marine fireworks, providing energy to marine ecosystems through photosynthesis.

2.Zooplankton: such as planktonic jellyfish, planktonic shrimp, Zhengxiao pelagic crab, planktonic conch, etc., they are consumers in the ocean, feeding on phytoplankton, and are also food for other marine organisms**.

3.Planktonic bacteria: such as heterotrophic bacteria, autotrophic bacteria, etc., they are microorganisms in the ocean that provide energy to the marine ecosystem by breaking down organic matter.

4.Zooplankton larvae: such as planktonic sea urchins, planktonic starfish, planktonic shellfish, etc.

Summary. Hello, I have seen your question and am sorting out the answer, please wait a while.

Why phytoplankton are small+ but producers of raw food in the ocean.

Hello, I have seen your question and am sorting out the answer, please wait a while.

Hello, phytoplankton are small but they reproduce and grow very quickly, although the biomass of this part of the phytoplankton is lower than that of predators, but the biomass of the biomass they reproduce is high enough to feed the predators. Phytoplankton grow fast, and less plankton grows faster. This is the law of the food chain, do you think you still have any questions that I need to answer for you?

The plants in the ocean are: green algae, mangroves, seaweeds, kelp, and seaweed.

1. Chlorella

There are more than 6,000 species of green algae, most of which grow in seawater lakes and a small part on rocks.

2. Mangrove forests

Mangrove is a tree species that grows in the sea, the highest growth height can reach about 5 meters, and the root system of the plant is relatively strong, there is a green canopy, when the tide will flood the rhizome, only the canopy of the mangrove forest is exposed on the sea surface.

3. Seaweed

Seagrass is an angiosperm that grows under the seawater, the root system is very well developed, can be a good protection for the habitat on the seabed, and seagrass likes a sunny environment, if the light is insufficient, there will be a thin growth.

4. Kelp

Kelp is a large perennial edible algae, the plant is a flat band, secretes mucus on the surface, is brownish-green in color, has two longitudinal grooves running through the middle of the leaf, and kelp grows mainly on rocks near the sea, and does not appear in deep water.

5. Seaweed

Seaweed is a seaweed that grows in the intertidal zone, and it is also the cultivated seaweed with the highest production value in the world, the color of the algae is black and purple, and it contains trace elements such as dietary fiber, vitamins, calcium, potassium, and magnesium.

1.The total amount of carbon sequestered by phytoplankton is greater than that of terrestrial plants worldwide.

2.Phytoplankton, although tiny, are (mainly) expanded by the ocean. After their death, the remains will form the "snow" of the sea along with it3The carbon we fix is lowered and accumulated on the seabed over the years, forming seabed oil.

They play an important role in regulating the temperature of the planet.

Your question has been answered (meow.

I'm very happy if I adopt it
