The largest ecosystem on earth is the biosphere; the most complex ecosystem is the tropical rainforest ecosystem. Humans mainly live in artificial ecosystems that are dominated by cities 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 risk of collapse; many basic substances continue to circulate in the ecosystem, of which the carbon cycle is closely related to the global greenhouse effect, and the ecosystem is ecological A major structural and functional unit in the field of science, which belongs to the highest level of ecological research.
