List the biotic components of the carbon cycle

Organisms eat plants, which is comprised of carbohydrates; those carbohydrates come from Carbon dioxide in the atmosphere. Thus, an abiotic factor (carbondioxide) helps create a biotic factor (the plants made out of carbohydrates).

Potassium-40 decays into argon gas over time.

Explanation: Potassium-argon dating is a dating method used to determine the age of sedimentary rocks by comparing the proportion of K-40 to Ar-40 in a sample of rock, and knowing the decay rate of K-40.

Potassium-40 undergoes decay following first order kinetics as given below:
