Wildflowers and Grass Snake and Hawk Rabbit and Mouse Grass and Mouse 2 / 15 Food chains show energy transfer between organisms. The size of a food chain can vary, yet there is a limit to the number of levels that a food chain can reach. Why is there a limit to the number of levels that a food chain can reach? Producers are limited by consumers. Energy is lost at each trophic level. Carnivores are too large to be eaten. Plants are not infinite in number. 3 / 15 It is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.
