In a nutshell: Animals grow and change through different stages, like eggs, young, and adults.
## Animals Change as They Grow
Just like plants, animals have life cycles too, but each animal’s life cycle can be very different!
## Stages of Animal Life Cycles
- **Egg**: Many animals begin as eggs.
- **Young**: Some hatch as tiny versions of adults, others look very different.
- **Adult**: Animals grow up and can have babies of their own.
## Amazing Transformations
Frogs start as eggs, become tadpoles (with tails and no legs), and then change into frogs! Butterflies begin as caterpillars, make a chrysalis, and transform into butterflies.
## Life Cycles Help Animals Survive
Each stage helps animals find food, stay safe, and grow strong.
## Real-World Connection
Learning about animal life cycles helps us take care of pets, protect wildlife, and understand nature.
Examples
- A butterfly starts as an egg, becomes a caterpillar, and then a butterfly.
- A frog lays eggs, hatches into a tadpole, then becomes a frog.
Key terms
