Carbon is present in the compound form in atmosphere ie., CO2, carbonates in water which forms limestone.

CO2 is taken by plants during photosynthesis to form organic compounds like glucose, carbohydrates, these plants are further eaten by animals, and decomposition gives CO2 back to the atmosphere. Plants and animals which get buried under the earth and does not decompose form coal and petroleum respectively.

Animals and plants also release CO2 back to the atmosphere during respiration.
