Definition of Prose. Prose is a communicative style that sounds natural and uses grammatical structure. Prose is the opposite of verse, or poetry, which employs a rhythmic structure that does not mimic ordinary speech.
Photosynthesis. Photosynthesis is the biochemical process that converts the energy of sunlight into organic compounds using carbon dioxide. Carbon dioxide (CO 2) reacts with water (H 2 O) in the presence of sunlight to form glucose (C 6 H 12 O 6) and oxygen (O 2).
Inside their cells, energy is extracted from the food in a process called cellular respiration. Cellular respiration requires oxygen (which is the by-product of photosynthesis) and it produces carbon dioxide, which is used in photosynthesis. In this way, photosynthesis and cellular respiration are linked in the carbon cycle.
