Final answer:
Different plant species have different responses to changes in temperature based on their adaptations and genetic makeup. Each plant form is adapted to specific environmental conditions and plants use feedback mechanisms to maintain their internal environments.
Step-by-step explanation:
The statement, 'Members of the same plant species always exhibit the same response to changes in temperature,' is FALSE. Different plant species can have different responses to changes in temperature depending on their adaptations and genetic makeup. For example, drought-resistant plant species would thrive in warm temperatures, while other species might decline in number in such a climate. It's important to note that each plant form is adapted to certain environmental conditions, and plants use negative and positive feedback mechanisms to maintain their internal environments and respond to external changes.
