How do polar bears illustrate the concept of adaptation?
How do polar bears illustrate the concept of adaptation?
- By migrating to areas with more food
- By maintaining their body temperature in extreme cold (correct)
- By developing a new diet in warmer climates
- By growing larger fur in the summer months

Study Notes
Species Adaptation to Environment
- Each species is uniquely adapted to thrive in its specific habitat.
- Polar bears exemplify adaptation, surviving in extremely cold Arctic conditions.
- Saguaro cactus exemplifies adaptation to deserts, enduring high temperatures and aridness.
Importance of Adaptation
- Adaptation is a fundamental concept in biology.
- It involves acquiring traits essential for a species' survival in its environment.
Two Uses of "Adapt"
- Acclimation refers to the short-term adjustment of an individual organism to a changing environment.
- Acclimation allows organisms to respond to immediate environmental changes.
Example of Acclimation
- Houseplants illustrate acclimation when transitioning from indoor conditions to full sunlight in spring.
- Leaves may get damaged without protective adaptations.
- Over generations, houseplants develop thicker cuticles and denser pigments for sun protection, though individual plants must adapt anew each season.
