Answer 1

Hint: Life span of any organisms is the theoretical number which tells about the number of years it can live. It can be calculated by the average lifespan of the organism. Timing of birth in different organisms is so poor criteria. Different species, different sizes, and their different habitats are some factors that organisms have different life spans.

Complete step by step answer: Life span can be defined as the period between the births to natural death of a living organism. Life span of an organism depends on its type. It can be from a few days to several years. It is a commonplace that all organisms die.
Crocodiles have different life span according to their habitat. Saltwater crocodiles can live approximately 70 years if they are not hunted by hunters.
