Where does the carbon cycle end? My project asks this, but I can of no specific "ending."
Think of a bicycle wheel. It's round and has no end.
Cycles don't have ends; they just keep going around and around.

That's why I'm confused. I'm asked about where it ends, and it is not exactly an open-ended question.
Check your textbook carefully to see if there's an explanation about the end of the carbon cycle. If you don't find it there, please ask your teacher about the meaning of this question.
There isn't. However, it's most likely to end up in the atmosphere.
The carbon cycle is a continuous process and does not have a specific "ending" point. It is a natural cycle that involves the movement of carbon between different reservoirs, or "sinks," in the Earth's atmosphere, land, oceans, and organisms.
To understand where the carbon cycle "ends," we need to look at the different components of the cycle and how carbon moves among them. Here is a simplified overview:
1. Carbon Dioxide (CO2) enters the atmosphere through various sources, such as respiration, volcanic eruptions, and human activities like burning fossil fuels.
2. Plants take in CO2 through photosynthesis, converting it into glucose and other organic molecules. This process helps to remove carbon from the atmosphere.
3. Carbon is then stored in plants as organic matter through processes like plant growth and the formation of plant biomass.
4. When plants and trees die, they can decompose or be consumed by animals. The carbon stored in these organisms is released back into the atmosphere through processes like respiration and decay.
5. Some carbon can be stored in the soil through processes like the decomposition of organic matter or the formation of carbonates.
6. Carbon can also be stored in the oceans in the form of dissolved CO2, as well as in marine organisms like phytoplankton and coral reefs.
7. Over long periods of time, carbon can be stored underground in the form of fossil fuels like coal, oil, and natural gas.
8. When fossil fuels are burned for energy, carbon is released back into the atmosphere as CO2, contributing to the increase in atmospheric carbon dioxide levels.
As you can see, the carbon cycle is a continuous loop with carbon moving among different reservoirs. While there are certain points where carbon can accumulate or be stored for longer periods (e.g., fossil fuels or carbon stored in rocks), there is no definitive "ending" point in the cycle as carbon continues to circulate and interact with different components of the Earth system.
For your project, you can explain how the carbon cycle operates as a dynamic process with carbon continually moving and exchanging among different reservoirs, without a specific endpoint.
