thanks!

 

Thank you!

Which of the following are consumers? Choose all that apply.

 

I have chosen all of them but the plants because they are producers? I am not too sure on the prey option very vague I think what kind of prey? It could be a rabbit, which is a consumer of plants. OR does it mean consumers in this context? That would include only predator, herbivore, parasite only. pls help

Predator Herbivore Prey Parasite Host Plant

Hello!

I think the answer is E? pls help

 

 

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

A tomatoes must have other defenses in addition to trichomes and “inhibitors”. B there has been herbivore-plant co-evolution between hornworms and tomatoes. C trichomes are not effective defenses against hornworms. D trichomes must be inducible defenses. E trichomes are constitutive defenses while “inhibitors” are induced defenses.
