Biological control agents are used in a wide range of contexts to limit damage from pests. However, the broader ecological consequences of such agents often are unclear before ecological risk assessments are performed. This Figure Set guides students to think through potential consequences of using biological control agents, and then uses a specific study to challenge students to interpret results from laboratory and caged field experiments. This Figure Set also introduces the concept of functional responses to students.
biological control agents, functional responses, predator-prey relationships, ecological risk assessments
Think-pair-share, drawing predicted results, designing experiments
answering questions on a worksheet, sharing responses with the class, and completing post-class homework that assesses understanding of key concepts
