Question
All living organisms contain carbon. As organisms grow, they require large quantities of carbon to carry out life processes and make new cells. Where is the source of most of Earth's available carbon?
Carbon atoms are constantly transferred from the Sun to Earth along with sunlight.
New carbon atoms are constantly being created by the process of photosynthesis.
Carbon is constantly recycled from dead organisms back into the environment.
Carbon is constantly transported from the mantle to the crust by volcanic eruptions.

The source of most of Earth's available carbon is best described by the statement:
**Carbon is constantly recycled from dead organisms back into the environment.**
This reflects the carbon cycle, where carbon is continuously exchanged between living organisms, the atmosphere, and the Earth's surface. Carbon is returned to the environment through processes such as decomposition, where dead organisms break down and release carbon back into the soil and atmosphere, making it available for new life forms.
