Quizplus · Accepted Answer

The increased production of alkaloids in response to herbivory is an example of induced plant defense, where the plant responds to environmental stressors (in this case, herbivory) by producing compounds to deter or repel attackers. Constitutive plant defense refers to the innate physical or chemical traits that a plant possesses regardless of external factors. Environmental challenges and incidental events are not relevant in this context. Hyperaccumulation process involves plants absorbing and accumulating toxins or heavy metals, which is not applicable here.
