Cellular respiration is the process that is used by organisms to convert complex molecules into carbon dioxide and water molecules. A biomolecule is a large organic molecule found in living systems. A carbon cycle is the movement of carbon atoms within the Earth's ecosystems. In photosynthesis carbon dioxide goes in the plant, photosynthesis occurs, and oxygen gas and carbohydrates leave the plant. Global warming is the observed and predicted increases in average global surface temperatures.
