Why were there no limits on the amount of calories given to plants?

Plants do not have a caloric requirement like animals do, as they produce their own energy through photosynthesis. The concept of calories is primarily relevant to organisms that consume food for energy. Therefore, when discussing the provision of nutrients or energy to plants, it’s more about ensuring adequate sunlight, water, and minerals rather than limiting caloric intake. Additionally, plants can utilize an abundance of sunlight and nutrients for growth without the constraints associated with calorie consumption in animals.
