What Are the Different Ecology Jobs?
The word ecology now usually refers to the living conditions of living things. It refers to the state of living and developing in a certain natural environment, and also refers to the physiological characteristics and living habits of living things. The word "Eco-" is derived from the ancient Greek word meaning "house" or our environment.

Definition of Ecology
- Chinese name: Ecosystem
- English name: ecosystem
- Definition 1 : A natural system that interacts with a biological community and its geographical environment. It consists of four parts: producers (green plants), consumers (herbivores and carnivores) and decomposers (saprophytes) of inorganic environmental organisms.
- Subjects: Atmospheric science (first-level discipline); Applied meteorology (secondary discipline)
- Definition 2 : A system composed of a biological community and the natural environment with which it interacts and the processes of energy flow in it.
- Subjects: Geography (first-level discipline); Biogeography (second-level discipline)
- Definition 3 : Within a certain spatial range, all biological and abiotic factors form a unified whole that is related to and interacts with each other through energy flow and material circulation processes. Subjects: Entomology (first-level discipline); Insect ecology (second-level science)

Ecological ecology introduction
- Ecosystem (ecosystem) refers to a unified whole composed of biological communities and inorganic environments. The scope of ecosystems can be large or small, interlaced with each other. The largest ecosystem is the biosphere; the most complex ecosystem is the tropical rain forest ecosystem. Humans mainly live in artificial ecosystems, mainly urban and farmland. The ecosystem is an open system. In order to maintain its own stability, the ecosystem needs to continuously input energy, otherwise there is a danger of collapse; many basic materials continue to circulate in the ecosystem. The carbon cycle is closely related to the global greenhouse effect. The ecosystem is ecological A major structural and functional unit in the field of science, belonging to the highest level of ecological research.
Eco- Ecosystem History
- In 1935, British ecologist Sir Arthur George Tansley was accepted by Danish botanist Yevgen Niven
- "(Original ) Ecosystem is the whole system, ... including not only the organism-complex, but also the whole complex of physical factors forming what we call the environment ..." (The ecosystem is a 'system' Including organic complexes, but also the entire physical factor complex that forms the environment ... This system is the basic unit of nature on the surface of the earth, and they come in all sizes and types).
- Stanley conducted an in-depth examination of the composition of the ecosystem and defined the ecosystem precisely.
- In the 1940s, American ecologist RL Lindeman discovered the basic characteristics of the energy flow of the ecosystem after quantitative analysis of Cedar Bog Lake:
- Irreversible transfer of energy in the ecosystem;
- · Progressively decreasing during the process of energy transfer, the decreasing rate is 10% 20%;
- This is also known as Lindemann's law.
