The right answers are : atmosphere and photosynthesis.

The basic process of short-term carbon recycling is the photosynthesis-respiration couple, that is, the conversion of CO2 to organic carbon through photosynthesis, and subsequently the reverse, the conversion of organic carbon to matter. organic CO2 by breathing. There are three basic reactions to consider.

First, photosynthesis that uses solar energy to synthesize organic matter by fixing carbon in carbohydrates (CnH2nOn).

Consumers draw their energy from that contained in primary producers by ingesting their tissues and breathing. Respiration is the opposite of photosynthesis: from O2 free oxygen, it transforms all organic matter into CO2 to return to the atmosphere.
