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.

Marine algae are chlorophyll-bearing, autotrophic, embryoless phyllophyllous marine spore plants. Referred to as seaweed. Features of seaweed:
The entire algae has the function of absorbing nutrients, carrying out photosynthesis, and producing nutrients. Although some seaweeds have a structure similar to the roots, stems, and leaves of higher plants, they are fundamentally different in terms of basic structure and function.
There are more than 10,000 species of plants growing in the ocean, and the vast majority of them are algae. These algae mainly include green algae, yellow algae, golden algae, brown algae, dinoflagellates, diatoms, red algae, cyanobacteria, euglena algae, etc. For example, kelp and wakame are plants of the brown algae family.
Seaweed can be consumed directly by humans. According to statistics, there are nearly 100 kinds of edible seaweed in the world, among which the green algae of Ulva, Ulva, Ulva, Reef Membrane, Kelp and Wakame of brown algae, and the seaweed and palm algae of the Red Algae phylum are all famous. At the same time, seaweed has a long history of medicinal use.

Photosynthesis. Microalgae in the ocean can photosynthesize very efficiently.
The microalgae in the ocean can photosynthesize very efficiently, and the resulting organic matter is continuously transferred through the food chain in the ocean, and finally the state is rich in fishery resources. Photosynthesis is usually the process by which green plants (including algae) absorb light energy, synthesize carbon dioxide and water into energetic organic matter, and release oxygen at the same time.
Theoretically, macroalgae such as these could restore homeostasis to marine ecosystems by reducing the amount of reactive oxygen species (ROS) in the ocean. Most of the antioxidant active substances found in macromarine algae mainly belong to the following categories, including carotenoids, phenolic compounds, phycocyanins, polyphenolic compounds, sulfate compounds, polysaccharide compounds, and vitamins.

Microalgae in the ocean are very efficient at photosynthesizing to produce organic matter.
Marine algae refer to chlorophyll, autotrophic and embryoless phyllophyllous marine spore plants. Referred to as seaweed. Features:
The entire algae have the function of absorbing nutrients, carrying out photosynthesis, and making nutrients. Although some seaweeds have a structure similar to the roots, stems and leaves of higher plants, they are fundamentally different in terms of basic structure and function.
The microalgae in the ocean can be permeable or photosynthesize with great efficiency, producing organic matter that is continuously transferred through the food chain in the ocean, resulting in a rich fishery resource. Photosynthesis is usually the process by which green plants (including algae) absorb light energy and synthesize carbon dioxide and water into energetic organic matter, while releasing oxygen.
The process by which green plants use the sun's light energy to assimilate carbon dioxide (CO2) and water (H2O) to make organic matter and release oxygen is called photosynthesis. The organic matter produced by photosynthesis is mainly carbohydrates and releases energy.
Seaweed is an important living marine resource. Seaweeds have chlorophyll and other pigments, are capable of photosynthesis, and are primary producers of organic matter in the ocean. The organic matter they create and the energy they accumulate are the basis for the survival and development of the entire marine biological world.
The oxygen produced by seaweed photosynthesis is extremely important for oxygen in the atmosphere and seawater**.
Ecosystem refers to a unified whole composed of organisms and the environment in a certain area A complete ecosystem includes the biological part and the abiotic part, and the biological part includes producers, consumers and decomposers The abiotic part is the inorganic environment such as water, air, soil, temperature, and light >>>More

The role of the urban ecosystem is to organize social production, facilitate the life of residents, and provide guarantee for economic and social development, which is embodied in four aspects: production function, life function, restoration function and regulation function. These functions are the flow of matter, energy, and information through the system and beyond. >>>More
