On the basis of intracellular organization what are two different categories of living organisms.

Answer the following Read the paragraph and answer the questions given below it. A biotic carbon atoms are circulated into the biotic form through processes like photosynthesis and respiration. Green plants convert carbon dioxide into carbohydrates and also produce carbon compounds like proteins and fats. Biotic compounds are transported from plants to apex consumers through intermediate trophic levels. After the death of all types of consumers, carbon is recycled by biotic decomposition. The carbon recycled in this way goes into the atmosphere and can be taken up by living organisms thus ensuring circulation and recycling of carbon in the biosphere. What process plays a significant role to ensure that carbon is available to living organisms even after the death of apex consumers?
