Oh, a million ways! The biggest is probably burning of coal and other fuels, but decomposition of plants and animals also returns carbon, and old trees often give out more carbon than they take in. So: burning, decomposition, respiration.
Answer:
Carbon dioxide, water, and sunlight are the raw materials for photosynthesis. Photosynthesis is the process by which green plants make their own food from carbon dioxide and water in the presence of sunlight. The prepared food is glucose. To prepare one molecule of glucose, by the process of photosynthesis six molecules of carbon dioxide and six molecules of water is required. Six oxygen molecule is released as a byproduct.
Thus, the correct product are 'Carbon dioxide, water, and sunlight'.
Explanation:
1. Some enzymes catalyze reactions that can run in either direction.
2. A product in one process may be a reactant in the next process.
I believe the correct answer is theory
