Answer:
Carbon cycle processes
Carbon moves through Earth’s ecosystems in a cycle referred to as the carbon cycle. It is through carbon dioxide gas found in Earth’s atmosphere that carbon enters the living parts of an ecosystem.
Plants use carbon dioxide to produce sugar—a process called photosynthesis. Sugars are carbon compounds that are important building blocks in food and all living matter. Food supplies the energy and materials living things need to live and grow. To release the energy in food, organisms break down the carbon compounds—a process called respiration. Carbon is released and cycled back into the atmosphere as carbon dioxide. When living things die and decay, the rest of the carbon that makes up living matter is released.
