Food energy is chemical energy that animals (including humans) derive from food through the process of cellular respiration. Cellular respiration may either involve the chemical reaction of food molecules with molecular oxygen[1] (aerobic respiration) or the process of reorganizing the food molecules without additional oxygen (anaerobic respiration)
Plant's grow better in sunlight its a given fact. artificial is limited and costs quite a bit while sunlight has no cost and is what plants naturally use to grow.
