Warm-blooded and cold-blooded animals

Learning goals

• I can describe respiration in organisms and explain the relationship with physical activity using theterms 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)
  

What adaptations do animals
have to survive in the cold

Why is it that birds and mammals are virtually the only animals living in the polar regions for most of the year?

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

Because of their habit of roosting together in large groups, bats are very vulnerable. If their rest is disturbed, an entire colony can be destroyed. There are not many good daytime resting places (hollow trees) nor many good places to hibernate through the winter where they will not be disturbed and where the winter temperature does not fall below freezing. During hibernation, bats live from the food reserves they have stored in their bodies. 

In Limburg, a number of bunkers from the Second World War have been set up as places where bats can spend the winter. 

What happens to the body temperature of bats that are woken up during hibernation?

Explain why bats that are disturbed multiple times during hibernation are more at risk of dying during a long winter than bats that are not woken up.

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

The artic fox has developed small ears to reduce heat loss

4. 350

01:04

During flight, how long does it take for birds to lose up to 1% of their body weight?

1. 1/2 hour
2. 1 hour
3. 12 hours
4. 24 hours

02:41

What proportion of birds that migrate in the fall return to breed the following spring?

1. 1/10
2. 1/4
3. 1/2
4. 3/4

02:43

Building collisions are responsible for nearly _____ bird deaths every year.

1. 100.000
2. 500.000
3. 1 million
4. 1 billion

03:00

What other services do birds provide?

1. insect control
2. pollination
3. dispersing seeds

03:54

While migration is one way to avoid the hardships of winter, many animals as well as some bird species have found ways of adapting to limited food and cold temperatures without needing to leave their homes. What are some examples of how species tough it out through difficult times?

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

Marine iguanas

Marine iguanas live on the Galapagos Islands. Like most reptiles, they often bask in the sun to warm up. Once they are sufficiently warm, they dive into the water and go looking for food. Marine iguanas graze on the algae on rocks on the seabed. They often can't do this for more than an hour or so because the water is cold. Then they come back up and find a spot on the warm rocks. 

Are marine iguanas cold-blooded or warm-blooded?

1. warm-blooded
2. cold-blooded

Explain the advantage to marine iguanas of warming up in the sun first before they go in search of food.

Which frog has the higher body temperature?

1. frog in container 1
2. frog in container 3

Drag the  green square to the container where most respiration takes places, and the orange 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?
