Question

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. (4 points)

Answer 1

can you make that more simple

Answer 2

Dragonflies may control their body temperature by perching in an obelisk pose as it allows them to minimize direct exposure to the sun's rays. This position enables them to reduce heat absorption from the ground, thus preventing overheating. Additionally, by raising their abdomens, they can expose a larger surface area to air currents, facilitating evaporative cooling. This posture also helps to direct heat away from the internal organs, allowing them to regulate their body temperature effectively.

Answer 3

Dragonflies perch in an obelisk pose to control their body temperature. This position helps them minimize sun exposure, preventing overheating. By raising their abdomens, they can cool down by exposing a larger surface area to air currents. This posture also helps in directing heat away from their internal organs, helping them regulate their body temperature effectively.
