Read the paragraph and answer the question-photosynthesis is a process in which radiant energy from sun is stored as chemical energy , which in turn is used to decompose carbon dioxide and water. The product of their decomposition are recombined into a new compound which successively builds, up into more and more complex organic substances like sugars, starches and cellulose that comprise the plant.The word stored in the paragraph is closest in morning to
