Robert Denno's studies on sap-sucking planthoppers showed that these species engage in _______ as a response to competition.

Question

Quizplus · Accepted Answer

Sap-sucking planthoppers engaging in resource partitioning is the most likely response to competition, as they divide up the limited resources (sap from plants) to avoid direct competition with each other. Option A (character displacement) and option C (niche realization) refer to longer-term evolutionary and ecological patterns that may occur as a result of competition, but are less likely to be observed directly as a response to competition in a particular population or community. Option B (antagonistic interactions) and option D (reciprocal adaptations) may also occur in response to competition, but do not specifically address how sap-sucking planthoppers partition resources.
