Solar energy is utilized to convert inorganic carbon, in the form of carbon dioxide, into organic carbon compounds, such as glucose. This is part of the carbon cycle on Earth; a cycle which demonstrates the law of conservation of matter. What process is responsible for inititating this cycle? A) Decomposition B) Photosynthesis C) Precipitation D) Respiration

B) Photosynthesis The Sun is the ultimate source of all energy in the universe. Plants being the main primary producers or autotrophs, use solar energy to make their own food through photosynthesis, thus converting energy into the organic matter that can be consumed by all organisms. They form the basis of almost all food chains from where consumers derive their food.
