Question

Which step is not involved in carbon cycle?

• A. Photosynthesis
• B. Respiration
• C. Transpiration
• D. Combustion of fossil fuels

Answer 1

The correct option is C Transpiration

Carbon cycle is the biogeochemical cycle which helps in the recycling of the nutrients. The carbon dioxide from the atmosphere is used by the plants for photosynthesis to prepare food and oxygen is released. The animals feed on plants as well as use oxygen for respiration and release carbon dioxide. The fossil fuels are made up of hydrocarbons which are burned for energy. The carbon particles, carbon dioxide and monoxide gases are present in the fumes on burning the fuels. Transpiration is not involved as a part in the carbon cycling.

Thus, the correct answer is option C.
