Carnivorous plant because light will be more limiting than nutrients. A plant can grow at zero investment in carnivory; this is also the "optimum" investment for a plant, as any investment in traps reduces net photosynthesis (growth) to less than the net photosynthesis of a plant that obtains its nutrients from soil alone. Carnivorous plants exist between these two extremes: the less limiting light and water are, and the more limiting soil nutrients are, the higher the optimum investment in carnivory, and hence the more obvious the adaptations will be to the casual observer. The most obvious evidence for this model is
Natural foods the term if the food does not contain added color, artificial flavors, or synthetic substances." Furthermore, the FDA has not developed any rules or regulations on the defining features of what qualifies a product as "natural." The FDA does reference a definition of "natural" in their informal policy (Ref. 53) that defines "natural" as "nothing artificial or synthetic (including colors regardless of source) is included in, or has been added to, the product that would not normally be expected to be there." The Food, Drug, and Cosmetic Act prohibits labeling that is false or misleading. The USDA's Agricultural Marketing Service
