Select the WRONG statement regarding carbon cycle.

Options

  1. AOceanic water can retain upto 50 times the C O 2 levels in the air.
  2. BThe only major reservoir of carbon in the biosphere is the lake.
  3. CVolcanic eruptions, hotsprings, burning of fossil fuel and weathering add carbon dioxide into the atmosphere.
  4. DThe recycling of carbon is a self regulating feedback system.

Correct answer

D. The recycling of carbon is a self regulating feedback system.

Step-by-step solution

The carbon cycle is a gaseous cycle and in the atmosphere carbon dioxide is 29 percent. In the ocean,71 percent carbon dioxide is present in dissolved form. The carbon reservoir is lithosphere so their circulation is self-regulating but recently carbon cycling is getting disturbed due to the combustion of fossil fuels and rapid deforestation. So the correct option is D.
