How do all animals and humans relate to the carbon cycle?

All animals and humans are integral to the carbon cycle through processes like respiration and decomposition. Animals, including humans, inhale oxygen and exhale carbon dioxide during respiration, which plants then use for photosynthesis to produce oxygen and organic matter. When animals die, their bodies decompose, releasing carbon back into the soil and atmosphere, further contributing to the cycle. This interconnectedness emphasizes the vital role of all living organisms in maintaining ecological balance and supporting life on Earth.
