Study Notes
Life Cycle
- A life cycle refers to the stages a living thing goes through from birth to death.
- The number of stages and the length of the life cycle depends on the species, or type, of animal.
Stages of Life Cycle
- Birth: The stage where an animal is born, either from an egg or through live birth (in mammals).
- Young: The childhood stage where animals do the most growing and developing, and focus on maintaining a supply of food, water, and shelter.
- Reproduction: The stage where an animal reaches adulthood, finds a mate, and reproduces to make more animals like them.
- Death: The final stage of every life cycle, where the amount of time an animal lives depends on its size, whether it is warm or cold-blooded, and its health.
Examples of Life Cycles
- Monarch butterfly: 4 stages, lives for a few weeks.
- Elephant: 3 stages, lives up to 70 years.
Birth Stage
- Most animals begin life inside an egg, a protective shell around the unborn animal.
- Birds, fish, and reptiles lay eggs to begin the life cycle.
- Mammals have live births, where the baby is born from the mother's body.
Young Stage
- Mammals, fish, reptiles, and birds have one stage of childhood where they look like a smaller version of an adult.
- Amphibians and insects go through metamorphosis, or a change in the way they look as they grow in the young stage.
Reproduction Stage
- Animals find a mate to reproduce with and make more animals like them.
- In some species, males have bright colors or other features to attract females.
- Some animals do a dance together after mating.
