Adaptationto

environment.

• 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)

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.

Adaptation to environment

How are Flounders specially adapted to their environment.

Adaptation to environment

Environment – water.

Adaptations• Flat (aid ability to hide from

predators)• Colour (camouflage)

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

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.
