short and in a way a 6th grader can understand no points

Answer 1

The carbon cycle is how carbon moves between the air, water, rocks, and living things. If there were no biosphere (no plants or animals), carbon would still cycle a little through volcanoes, the ocean, and rock weathering, but it would be much slower and simpler. Living things make the carbon cycle faster and help pull carbon out of the air into plants and soil. So the biosphere is not strictly required for a carbon cycle, but it makes the cycle stronger and helps keep Earth’s climate steady.
