You are studying the effects of tomato hornworms (herbivores) on tomato plants in a laboratory experiment. tomato plants have trichome defenses (small hairs) and chemical defenses (called “inhibitors”) that interfere with digestion by the herbivore. from your experiments, you discover that the number of trichomes on leaves is unchanged after feeding by hornworms whereas the concentration of “inhibitors” increases. from this experiment you can conclude that
