Notice that photosynthesis and respiration are essentially the opposite of one another. Photosynthesis removes CO2 from the atmosphere and replaces it with O2. Respiration takes O2 from the atmosphere and replaces it with CO2. However, these processes are not in balance.
Photosynthesis followed by death of the plants and several geological processes lead to the formation of petroleum. This also removed Carcon dioxide from the atmosphere.

In addition to photosynthesis, a lot of CO2 gets removed from the air-water system during deposition of carbonate minerals in and as sediments.
