Which describes a possible path a carbon atom could take through the carbon cycle? O A. Decomposers make coal into carbon. Carbon is released into the atmosphere. Plants take in carbon. Plant matter forms coal.
O B. Plants containing carbon die. Decomposers break down plant matter. Plant matter forms coal. Humans burn coal that releases
carbon into the atmosphere.
OC. Plant matter breaks down carbon in coal. Humans burn coal that releases carbon into the atmosphere. Decomposers break down
carbon in the atmosphere. Carbon in the atmosphere forms coal.
D. Humans burn coal that releases carbon into the atmosphere. Decomposers break down carbon in the atmosphere. Plant matter
breaks down carbon in the atmosphere. Plants containing carbon die.

Achemical reaction (also known as a chemical change) produces substances that are chemically different from the starting materials. an example of a chemical reaction is the formation of water from hydrogen and oxygen gas.in a physical change, a substance changes its physical appearance but not its chemical identity. an example of physical change is the formation of liquid water from solid water, a familiar process called melting. physically, liquid water looks very different from solid water (ice) but the chemical identity, water, is the same for both. which of following changes that affect the composition of our atmosphere involve physical changes and which involve chemical reactions? oxygen gas changes to ozone during thunderstorms carbon dioxide is produced by the combustion of gasoline in an automobile engine. when coal, oil, and natural gas are decomposed in landsills they produce methane gas. freezing rain develops when a warm air mass overrides a cold air mass. fog forms from water vapor when the temperature drops below the dew point
