Name the four things that can happen to move carbon from a plant and return it to the atmosphere

1. Respiration-process by which plants release CO, while they break down the sugar

2. Animals eat plants - They break down sugars and starches by a process of metabolism and the products are energy water, and CO2 molecules.

3. Decomposition-when plants die, their parts (wood, leaves) decay bringing the carbon into the ground

4. Root respiration - respiration that occurs in roots, adds to soil respiration (the amount of CO2 produced through root respiration is determined by the root biomass).
