For growth to occur in organisms, the rate of anabolism must exceed that of catabolism.
Anabolism is the process by which cells build up complex molecules, such as proteins and carbohydrates, from simpler precursors. Catabolism, on the other hand, is the process by which cells break down complex molecules into simpler components to release energy.
In order for growth to occur, the rate of anabolism must be greater than the rate of catabolism, meaning that the organism is synthesizing more new material than it is breaking down. If catabolism exceeds anabolism, the organism will break down more material than it can replace, leading to a net loss of mass.
Food storage levels do not directly impact growth, as growth can occur in organisms with both high and low food storage levels.
In summary, for growth to occur in organisms, the rate of anabolism must exceed that of catabolism, regardless of food storage levels.
