Unit 1 Basic 8

Warm-blooded and cold-blooded animals

Learning goals

• I can describe respiration in organisms and explain the relationship with physical activity using the terms glucose, oxygen, water, carbon dioxide, energy
• I can describe the differences in respiration between cold-blooded and warm-blooded animals
  

What is the formula of respiration (= combustion in your body)? 

Glucose

Oxygen

Energy

Carbon dioxide

Water

Combustion in your body = respiration

Getting energy from food 

• Our fuel is glucose
  
• Oxygen is needed to break down glucose (breathing)
  

Energy in our body
is used for?

Energy is used for

-contraction of muscles

-Transporting chemicals

-Absorbing food

-Sending messages along nerves

-Building new cells for growth

-Keeping a constant body temperature

What adaptations do animals
have to survive in the cold

Living in an extreme cold environment

Adaptations: Isolation

Bats hibernate: they sleep during the ENTIRE winter

Squirrels fake hibernate: they sleep during winter, but wake up sometimes to eat

To which type of hibernation does the graph belong?

1. True hibernation
2. Fake hibernation

The Fennec fox has developed large ears to give off heat better

The artic fox has developed small ears to reduce heat loss

which dog cools down the least quickly? Explain why

Is the green line a warm-blooded or cold-blooded animal?

1. warm-blooded
2. cold-blooded

Drag the  green square to the container where most respiration takes places, and the blue circle where there is the least respiration

Why is it more likely to find a whale (marine mammal) around the poles, but unlike to find a shark around there?
