Choose the correct sequences
(a) in atmosphere → decomposers → organic carbon in animals → organic carbon in plants
(b) in atmosphere → organic carbon in plants → organic carbon in animals → inorganic carbon in soil
(c) Inorganic carbonates in water → organic carbon in plants → organic carbon in animals → scavengers
(d) Organic carbon in animals → decomposers in atmosphere → organic carbon in plants
Answer: B
Solution.
Nutrient cycling is a cyclic process that encompasses the movement of nutrients from the physical environment to living organisms and back to the environment. Nutrients are present on the earth where they are recycled, transformed into different forms and reutilized. Carbon is present mainly as carbon dioxide and methane in the atmosphere.
There is a continuous exchange of carbon between biotic and abiotic components by the process of photosynthesis and respiration.
Slow geological processes, including the formation of sedimentary rock and fossil fuels, contribute to the carbon cycle over long timescales.
Hence, the correct option of this question is option B
