• Adaptation is the development of special characteristics by plants or animals to suit a particular environment.

Adaptation to environment
Animals and plants evolve to suit their environment to increase their chance of survival.

• How are the following species adapted to their environment.
• Think about– the environment they live.– What features allow them to survive in that
environment.

Adaptation to environment
Polar BearEnvironment – Extreme cold, snow and ice.
Adaptations• Feed their young (better
chance of survival)
• Small ears (reduce heat loss)
• Thick layer of fur (warmth)
• White fur (camouflage)
• Wide feet (for support on soft snow)
• Sharp teeth (eat prey)
6
Adaptation to environmentEnvironment – desert and arid (dry).
Adaptations• Can survive up to 8 days without
water.
• Broad, soft feet (support on soft sand)
• Humps contain fat (energy store)
• Diet (thorny plants, seeds, dry leaves, bones)
• Hair (short, thick and dense – protects skin from sunburn)
• Long eyelashes (protect eyes from sand)
Camel

Fish Environment – water Adaptations
• Gills (remove oxygen from water and release carbon dioxide from the blood)
• Streamlined shape (reduces drag when swimming)
• Mucus covered scales (reduces drag when swimming)
• Large number eggs produced (increase survival as many eaten by predators.

How are Flounders specially adapted to their environment.
Adaptation to environment
Environment – water.
Adaptations• Flat (aid ability to hide from
predators)• Colour (camouflage)
9
How are Sharks specially adapted to their environment.
Adaptation to environment
Environment – water.
Adaptations• Sharp teeth (to rip prey apart).
• Can survive for a long time without food.
• Smell blood from 5 miles away
• Sense electrical activity from movement of fish
10
Adaptation to environment
Environment – desert and arid (dry).
Adaptations• Small leaves, spikes (to reduce
water loss through transpiration).
• Waxy cuticle on leaves (to reduce water loss through transpiration).
• Extensive roots (to absorb water from deep underground).
Cactus

Adaptation to environment
Environment – Wet, pathways.
Adaptations• Strong roots (to prevent
removal)
• Flat leaves (to prevent removal)
How are weeds specially adapted to their environment.
