Choose the correct sequences:
CO2 in the atmosphere → organic carbon in plants → organic carbon in animals → inorganic carbon in soil
The correct answer is: C (CO2 in atmosphere → organic carbon in plants → organic carbon in animals → inorganic carbon in soil)
The explanation for Correct answer:
The correct sequence among the following is :
CO2 in the atmosphere → organic carbon in plants → organic carbon in animals → inorganic carbon in the soil.
The carbon dioxide in the atmosphere is converted into the organic compound by photosynthesis which is taken as food by living organisms such as animals, the organic compounds in the animals after their death is converted to inorganic carbon in the soil
The explanation for the incorrect answer:
(a) CO2 in the atmosphere → decomposers → organic carbon in animals → organic carbon
in plants:
The above sequence is not correct because the carbon dioxide in the atmosphere is not decomposed, it is converted into organic compounds class carbon which is utilized by other animals as food and after the death of the living organisms such as animals, carbon is released back to the atmosphere by Decomposition.
(c) Inorganic carbonates in water → organic carbon in plants → organic carbon in animals → scavengers
The water contains carbon dioxide seeps inside the earth and forms carbonate rocks, also termed inorganic carbonates through geological shifting the carbonates from the rocks enter the soil by weathering, this makes soil nutrition-rich which can be utilized by plants to make food.
(d) Organic carbon in animals → decomposers → CO2 in the atmosphere → organic carbon in plants
The organic compounds in the body of animals are decomposed by decomposers to release carbon dioxide into the atmosphere which is further utilized by green plants for photosynthesis to make the organic compounds of carbon.
