Life cycle of animals

1. Life cycle of animals By: Ashley Gilmer

2. What would you like to do??? Mammals Quiz Amphibians Insects

3. !Mammals!

4. What is a mammal?? • They are warm blooded, which means that they can regulate their body temperature! • Have hair and ear bones • They give birth to live young, which means that the babies do not pop out of an egg. • YOU ARE A MAMMAL!!!

5. Growing up mammals • Females grow their babies inside of them • Once the baby is born, the mother takes care of their young for a while. Just like your mother takes care of you! • Mammals are the only animals that feed their babies by milk from their body.

6. Three different types of mammals!!!! Select the one you want to learn about first  Placental Marsupials Monotreme Menu

7. !Marsupials!

8. What is a marsupial?? • When the babies are born, they are not fully developed. • They are first put into their mothers pouch so they can finish growing. • A Kangaroo is an example!!

9. Monotreme

10. What is a monotrome?? • They are the only mammals that lay eggs • They only live in Australia and New Guinea • An Anteater is an example!

11. !Placental!

12. What is a placental? • Before the babies are born, they are nourished in a placenta • A placenta is where the baby is able to get everything it needs to grow while inside their mom.

13. Amphibians

14. What is an Amphibian?? • Amphibians are four legged animals. • They are cold blooded which means they cannot regulate their body temperatures. They are as cold or as warm as it is outside. • They can live on land or in water • They are able to breather with gills, lungs, and even through their skin!!!

15. Growing up Amphibians!! • Amphibians start out as tadpoles. You would probably think of a baby frog when you think of a tadpole. They look like a little fish which means they only have gills at this point. • As they begin to change, they go through a process called metamorphosis, which just means change

16. Growing up Amphibians contd. • When they reach their adult part of their life, they develop lungs so they can breathe on land. • Metamorphosis changes the physical shape and their feeding and breathing habits • It can take an Amphibian 3-4 years to become an adult.

17. EXAMPLES

18. Insects

19. What is an Insect?? • There are many different types of insects • They have three different body parts • Head • Thorax • Abdomen • They have an exoskeleton, which mean their skeleton is on the outside of their bodies instead of inside like yours.

20. Growing up Insects • Four stages • Egg>Larvae>Pupa>Adult Now lets talk about the first stage THE EGG

21. The Egg • The egg can be many shapes and sizes. • How many weeks or months the insect is inside the egg all depends on the type of insect it is. • Now lets go to the next stage: • Larvae

22. The Larvae • This is the stage where the insect begins to grow • It eats a lot of green foods that it can grow big and strong in order to change into an adult. Next stage: Pupa Q4

23. The Pupa • This is the stage where they begin to transform into an adult • Many insects use a chrysalis to help them change. • They can either grow wings or just continue to grow. • When this stage is complete, they split open the chrysalis so they can live their lives as an adult!! • Last stage • Adult

24. The Adult • Some have developed wings and some have just gotten bigger. • This is the final stage!!!!!!! • They have gone through a complete metamorphosis, just like Amphibians
