1132 - What is the lifespan of living things from birth to death, and how do they reproduce?
The lifespan of living things from birth to death is called the "life cycle". It's when an organism grows, reproduces, and eventually dies. Here's a simple overview:
- Birth: A living thing is born, either from a parent (animals) or seed/egg (plants).
- Growth: The living thing grows and develops, getting bigger and stronger.
- Reproduction: When it's ready, the living thing makes more of its kind, either by:
- Laying eggs (like birds, reptiles, and insects)
- Giving birth to live young (like mammals)
- Making seeds (like plants)
- Dividing cells (like some tiny animals and plants)
- Maturity: The new living things grow up and become adults.
- Old age: As the living thing gets older, it starts to slow down and its body starts to weaken.
- Death: Eventually, the living thing dies, and its body stops working.
That's the basic life cycle. It's a natural part of life, and it helps keep the world full of new and interesting living things.
