Solution
The correct option is A B is decomposition; C is respiration; D is respiration and E is photosynthesis.
Carbon is present in the atmosphere in the form of carbon dioxide and is utilised by the plants (producers) in the process of photosynthesis (E). All organisms (plants and animals) require energy for performing various body functions. This energy is produced by the process of respiration. As a byproduct of this process carbon dioxide is released (C) and (D). When plants and animals die, they are broken down into simple forms by the action of decomposers. This process is called decomposition.
