Unformatted text preview: utotrophs These organic compounds provide nutrients for chemoheterotrophs. • • Chemoheterotrophs release CO2 that is then used by photoautotrophs Carbon is removed from the cycle when it is i i incorporated in CaCO3 and fossil fuels t di d f els • Photosynthesis and respiration
• Collectively photosynthesis and Collectively, respiration control bioelemental cycling.
