carbon cycle

• Process that releases energy by breaking down glucose and other food molecules in the presence of oxygen

• process by which plants and some other organisms use light energy to convert water and carbon dioxide into oxygen and high-energy carbohydrates such as sugars and starches

• a species on which other species in an ecosystem largely depend, such that if it were removed the ecosystem would change drastically.

• the series of processes by which carbon compounds are interconverted in the environment, chiefly involving the incorporation of carbon dioxide into living tissue by photosynthesis and its return to the atmosphere through respiration, the decay of dead organisms, and the burning of fossil fuels.
