Unit 1 Basic 3

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

• Respiration = releasing the energy in your food to get energy. Oxygen is needed to break down glucose. CO2 and water are produced as waste products

• Food = Fuel = Glucose 

• Reaction equation: glucose + oxygen = water + CO2 + energy

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: Insulation

3. 12 hours
4. 24 hours

4. 350

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

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

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

What other services do birds provide?

1. insect control
2. pollination
3. dispersing seeds

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?
