What Major Ecological Roles Exist?

Ecosystem functions are the various functions or effects embodied by the ecosystem. It is mainly manifested in the aspects of biological production, energy flow, material circulation and information transmission. They are realized through the core of the ecosystem-biological community. Biological production is one of the basic functions of the ecosystem. Biological production is the process of converting solar energy into chemical energy, producing organic matter, and converting animal energy into animal energy. Biological production goes through two processes: plant production and animal production. The two kinds of production are linked to each other and exchange energy and matter, and at the same time, they are carried out independently. ^[1]

Ecosystem functional physical information

Physical information refers to information transmitted through physical processes. It can come from the inorganic environment or from the biological community. It mainly includes: sound, light, temperature, humidity, magnetic force, mechanical vibration, etc. P. 105). Eyes, ears, skin and other organs receive physical information and process it. Plant flowering is physical information.

Ecosystem Functional Chemistry Information

Chemical information ( chemical information ) Many chemical substances can participate in information transmission, including: alkaloids, organic acids and metabolites, etc. The nose and other special organs can receive chemical information.

Ecosystem functional behavior information

Behavior information ( behavior information )

Bee dance

Passed between the same species and one organism. There is a variety of behavioral information, such as the "circle dance" of bees and the "courtship display" of birds.

Ecosystem function

The activities of organisms in the ecosystem are inseparable from the role of information. The role of information in the ecosystem is mainly reflected in:

The normal progress of life activities

· The seeds of many plants (lettuce, eggplant, tobacco, etc.) must receive light information of a certain wavelength to germinate

· The wings of insects such as aphids can only be produced under specific lighting conditions

Optical information has a significant impact on the biological clock of various living things

· Normal living and predation are inseparable from various information such as light, smell and sound

Population reproduction

Light information has an important effect on the flowering time of plants

· Sex hormones play an important role in the breeding season of various animals

· The time for birds to reproduce is related to the length of sunshine

Adjust the inter-species relations of organisms to maintain the stability of the ecosystem

· On grasslands, when the grasslands return to green, "green" provides herbivores with information they can eat

· In the forest, the wolf can hunt the latter based on the smell left by the rabbit, and the rabbit can avoid hunting based on the smell or behavior characteristics of the wolf.
