12-6 How are organisms adapted to changes of season?
Aim: How are organisms adapted to changes of season?
OBJECTIVE: Describe seasonal adaptations of plants and animals.
Key Terms
axis (AK-sihs): imaginary line through the center of a planet around which that planet spins
insulation: a material that slows the transfer of heat
Lesson Summary
• Seasons are due to the tilt of Earth on its axis.
• The part of Earth that is tilted toward the Sun has more sunlight, stronger sunlight, and warmer
temperatures than the part tilted away from the Sun.
• Seasons change as Earth revolves around the Sun.
• Plants and animals have adaptations that help them survive seasonal changes.
• To survive cold weather, plants may shed leaves or die and depend on seeds and spores to
reproduce next season.
• In cold weather, animals may change colors to blend in with snow or eat more food to add insulation
to their bodies. Many animals reproduce in spring so their offspring will have a chance to grow and
develop before winter.
• Some animals survive winter by hibernating; others migrate to warmer climates where there is more
food.
