Transcript of Life cycles of some animals
What are the life cycles of some
animals?
1-the mother eagle lays an egg.2-the eaglet, a young eagle, develops inside the egg.3-The eaglet hatches when it is ready.
When the bear cub is born, it grows bigger and develop into adults.
Life cycle of a butterfly
1- Egg
A butterfly begins life In a tiny egg.
- A butterfly larva is called a caterpillar.- It hatches from an egg.-the caterpillar sheds its skin as it grows.- it has a worm-like body.- it must eat a lot to grow and store energy.
2- larva
3- pupa
-a butterfly pupa is protected inside a hard covering called chrysalis.-the insect grows wings and long legs.-it does not eat, and it hardly moves.
-the adult butterfly breaks out of the chrysalis.-It has wings,long legs,and antennae.-It flies away to find a mate.-It will lay eggs if it is a female, then it will die.-some of them feed on the nectar or flowers.
4- adult Butterfly
Life cycle of a frog
Some animals change form as they develop.Metamorphosis is the change in form during an animal`s life cycle.
-Mother frogs lay hundreds of eggs in the water.- the eggs are surrounded by a jellylike material.
1- eggs
- A tadpole hatches from frog egg.-Tadpole Lives underwater and breathes with gills.-It has a tail for swimming.
2-tadpole
-as it grows, it develops body parts for living on land.-it grows leg. The tail disappears. - Lungs replace gills.
3-growing tadpole
-The adult frog lives on land and in water.- It uses its leg to hop.-it lays eggs in water.
4- Adult frog
Life cycle of a
Mammal
- Young mammals do not change very much as they become adults.-They look like their parents when they are born.
- Young bobcats develop from eggs inside the mother`s body.-They are born when they are ready to live outside the mother`s body.
1- egg
-Young bobcats are called kittens. -The mother bobcat`s body makes milk. -The kittens drink the milk.
2-Kitten
-The young bobcats grow bigger. -The mother bobcat takes care of them.
3-growth
-when the young bobcats grow to be adult, they can reproduce.
4-adult
Most insects live for less than one year. Other animals live much longer.
Life span is the length of an animal`s life.
