What is the difference between freshwater ecosystems and marine ecosystems in the biosphere

The monosphere is the area on Earth where life is active, mainly in the range from a depth of 12 kilometers below sea level to an altitude of 10 kilometers above sea level. Almost everything that has life in the world is included in this range.

In the biosphere, the ecosystems are the conditions that animals, plants, microorganisms and their living and reproduction.

Ecosystems include producers (e.g. green plants and photosynthetic bacteria), consumers (e.g. herbivores and carnivores), decomposers (e.g. microorganisms) and inanimate matter (e.g. air, water, soil, sunlight, inorganics). The system is characterized by the circulation and exchange of matter and energy.

China's ecosystems mainly include forests, grasslands, deserts, farmland, wetlands, and oceans. In addition, there are bamboo forests and a variety of shrub ecosystems.

The marine ecosystem consists of two parts: the marine biome and the marine environment. Each part contains a number of elements. There are 6 main categories of these elements:

1. Autotrophs, as producers, are mainly plants with green pigments that can carry out photosynthesis, including planktonic algae, benthic algae and marine seed plants; There are also bacteria that can carry out photosynthesis.

2. Heterotrophs, for consumers, including all kinds of marine animals.

3. Decomposers, including marine bacteria and marine fungi.

4. Organic detritus matter, including organic detritus decomposed after the death of organisms and organic detritus imported from land, as well as a large number of dissolved organic matter and its aggregates.

5. Inorganic substances participating in the material cycle, such as carbon, nitrogen, sulfur, phosphorus, carbon dioxide, water, etc.

6. Hydrophysical conditions, such as temperature, ocean currents, etc.

Aquatic ecosystem is a dynamic equilibrium system with specific structure and function composed of aquatic biome and aquatic environment.

Aquatic ecosystems are the general term for various types of water ecosystems on the earth's surface. Aquatic ecosystems are inhabited by communities of autotrophs (algae, aquatic weeds, etc.), heterotrophs (various invertebrates and vertebrates), and decomposer organisms (various microorganisms). Various biological communities and their interactions with the water environment maintain specific material cycles and energy flows, constituting a complete ecological unit of the middle finger.

A continuum of interactions between biotic and biotic and abiotic factors in a water system. These include inland waters (lakes, reservoirs, rivers, wetlands, etc.), estuaries, and marine ecosystems.

China has marine ecosystems: mangrove deep-sea ecosystem, coastal wetland ecosystem, upwelling ecosystem, and coral reef ecosystem.

The marine ecosystem consists of four members: the inanimate marine environment (sunshades, air, seawater, inorganic salts, etc.), producers (marine plants), consumers (marine animals), and decomposers (microorganisms). These four members are interdependent, mutually restrictive, and mutually reinforcing.

Chain-related material circulation and energy flow in marine ecosystems:

1. The material cycle and energy flow of the marine ecosystem is a dynamic process, and a state of dynamic equilibrium will be reached without interference.

2. The material cycle and energy flow of marine ecosystems follow the law of "ecological pyramid". Taki is the producer of marine plants, which absorb solar energy from seawater, which is the energy base of the marine ecosystem. Above the base are consumers, who compete, prey, and restrain each other.

3. Located at the top of the tower are often the most exclusive consumers with very small numbers and only one shadow, such as sharks, marine mammals, seabirds, etc. <>
