What is Life Span? - Class 12 Biology - Reproduction in Organisms

The period from birth to the natural death of an organism represents its life span. The lifespan of an organism is not necessarily correlated with its body size, it can vary from less than one day to more than 400 years. Irrespective of the long or short lifespan of an organism, death is a certain phenomenon, i.e. no individual is immortal, except for single-celled organisms like Amoeba.
