- 6. Cold-blooded Animals • Theytake on the temperature of their surroundings • They are hot when their environment is hot and cold when their environment is cold • In hot environments can have blood that is much warmer than warm-blooded animals
- 7. • In warmenvironment more active • In cold environment sluggish and lazy – This is because their muscle activity depends on chemical reactions which run quickly when it is hot and slowly when it is cold. Period of inactivity is called aestivation (hibernation)
- 8. Warm-blooded Animals • Tryto keep the inside of their bodies at a constant temperature. – In a cooler environment by generating their own heat – In a hotter environment by cooling themselves when they are hot. • To generate heat, warm-blooded animals convert the food that they eat into energy.
- 9. Types of Food-eatingAnimals • Carnivorous Animals that eat other animals • Herbivorous only eat vegetables • Omnivorous eat both meat and plants

- 27. • Respiration Lungs • Hearing organs – Lack outer ears – Inner ear respond to vibrations • Capable of regeneration – Lizard • Longevity – Tortoise and turtles live up to 150 years – Crocodiles can live up to 100 years
