Question

explain how cellular respiration uniquely contributes to the carbon cycle. In 3–5 sentences, describe the different ways that both photosynthesis and cellular respiration contribute to the carbon cycle.(4 points)

Answer 1

Cellular respiration uniquely contributes to the carbon cycle by breaking down organic molecules, such as glucose, to release carbon dioxide (CO₂) back into the atmosphere. This process occurs in all aerobic organisms, including animals and plants, as they convert stored energy into a usable form while producing CO₂ as a byproduct. In contrast, photosynthesis absorbs CO₂ from the atmosphere and converts it into glucose and oxygen using sunlight, effectively removing carbon from the atmosphere and storing it in organic forms. Together, these processes create a cycle: photosynthesis captures carbon, while cellular respiration returns it, maintaining the balance of carbon in ecosystems.
