The stages that an organism goes through from birth to death are generally called its life cycle. This can be broken down into more specific stages depending on the organism and its complexity:

For animals, a common breakdown might be:

* Prenatal: This stage begins at conception and ends at birth. It may include embryonic development, gestation, and hatching.

* Neonatal: This is the first stage of life after birth, often characterized by rapid growth and dependence on parents.

* Juvenile: A period of continued growth and development before reaching sexual maturity.

* Adult: The stage where an organism is capable of reproduction.

* Senescence: The process of aging, often marked by a decline in physical and cognitive abilities.

For plants, the life cycle often includes:

* Seed: The dormant stage of the plant, containing the embryo.

* Germination: The process of the seed sprouting and developing into a seedling.

* Vegetative growth: A period of rapid growth and development of the plant.

* Reproductive stage: When the plant produces flowers, fruits, and seeds.

* Senescence: The gradual decline of the plant, leading to death.

Remember: These are just examples, and the specific stages and terminology can vary greatly depending on the type of organism.
