Dragonflies are flying insects. In the summer, dragonflies can be seen perched on tree branches in an obelisk pose (i.e., a handstand position with the tip of their abdomen pointing upward). In 3–5 sentences, describe how dragonflies might control their body temperature and give reasons for why they might perch in this pose.

Answer 1

Dragonflies control their body temperature through a process called thermoregulation. By perching in an obelisk pose with their abdomen pointed upward, dragonflies can minimize their exposure to direct sunlight and reduce heat absorption. This position helps to maintain a cooler body temperature, preventing overheating. Additionally, perching in an obelisk pose may also enable dragonflies to optimize sun exposure for increased warmth when needed, as they can adjust their body angle to maximize or minimize exposure to sunlight.
