Answer: Photosynthesis
Explanation: The carbohydrates in your diet are a product of photosynthesis.
Photosynthesis is the process by which plants, algae, and some bacteria convert light energy from the sun into chemical energy, which is stored in the form of carbohydrates (such as glucose). Carbohydrates are one of the three major macronutrients that are essential for human nutrition, and they are an important source of energy for our bodies.
While ingestion and mechanical digestion are important steps in the process of obtaining carbohydrates from our diet, the ultimate source of these carbohydrates is the plants and other photosynthetic organisms that produce them. Once we ingest the plant material, our bodies break down the carbohydrates through further digestion and cellular respiration in order to extract the energy they contain.
