The pink labels include the plants, organic nutrients, and inorganic nutrients. The blue labels include plant uptake, decomposition, erosion or leaching. The reservoir composed of organic nutrients in the soil being the largest reservoir of nutrients in the ecosystem. The ecosystem loses and gains nutrients through the reservoir composed of inorganic nutrients in the soil. The process of decomposition limits the rate of nutrient cycling in the ecosystem. The process of erosion or leaching results in the largest loss of nutrients from the ecosystem.
'The best answer is a lava flow. Primary succession happens in lifeless areas or regions where soil is not capable of sustaining life which may be caused by lave flows, retreating glaciers or newly formed sand dunes. It is one of the two types of biological and ecological succession.
During daylight hours, plants take in carbon dioxide and release oxygen through photosynthesis, and at night only about half that carbon is then released through respiration. However, plants still remain a net carbon sink, meaning they absorb more than they emit.
