Question

True or false: There is a constant amount of carbon on Earth. Carbon cannot be made or destroyed. It can only move between different carbon reservoirs.

Answer 1

true Because Earth is a closed system, the amount of carbon on the planet never changes. However, the amount of carbon in a specific reservoir can change over time as carbon moves from one reservoir to another. For example, some carbon in the atmosphere might be captured by plants to make food during photosynthesis
