Responses to the Environment

This study guide covers environmental sensing and communication in organisms, focusing on behavioral and physiological responses to environmental cues. Key examples include photoperiodism, phototropism, taxis, kinesis, and fight-or-flight. It also explores organism-to-organism communication (hormones, behaviors) and its connection to natural selection and cooperative behavior. Finally, it provides exam tips, common pitfalls, and practice questions related to these topics.
