Study Notes
Adaptation: Overview
- Adaptation involves changes to acclimate to new environments or situations.
Human Adaptation
- During winter, humans wear heavier clothing to maintain body warmth.
Plant Adaptation
- Chlorophyll, the green pigment in leaves, is essential for photosynthesis (food production).
- In autumn, shorter days and reduced sunlight lead to the breakdown of chlorophyll, causing leaves to change color (yellow, red, brown) and eventually fall off.
- During winter, the lack of chlorophyll results in dormancy, where plants become inactive.
- Plants re-emerge from dormancy in spring and summer, becoming active again.
Animal Adaptation
- Animals face food scarcity in winter and adapt through two primary strategies:
- Hibernation: Long-term state of reduced metabolic activity characterized by slow heart rate and breathing. Example species include bears and mice.
- Migration: Movement of large animals to different locations to access food or warmer climates during colder months.
