Biology Core

Cold Climates, adaptations include:

• Thick fur and blubber
• White in winter and brown in summer (camouflaged)
• Small ears

Dry Climates, adaptations include:

• Hunt or feed at night
• Large surface area (wrinkled skin)
• Large ears

Bigger animals have a smaller surface area compared to their volume therefore conserve heat more easily but it is also more difficult to lose heat.

• Plants must be adapted to live in a variety of climates including deserts
• Plants must also be adapted to survive being eaten by animals

Conserve water - e.g. cacti

• Extensive roots
• Waxy leaves
• Small leaves
• Water storage in stem

Protection From Predators

• Thorns
• Poisonous chemicals
• Warning colours

Animals compete for:

• Water
• Food
• Space
• Mates
• Breeding Sites

The most succesful ones survive and pass on their genes to  the next generation

Plants compete for:

• Water
• Nutrients
• Light
• Space

Successful plants have structures and habits that allow healthy growth
