Question

Which of the following has the longest life span?
A. Banyan tree
B. Tortoise
C. Parrot
D. Elephant

Answer 1

Hint:The life span of an organism is referred to as the period from birth to its natural death. Different organisms have different life spans based on their genetic and physiological functions. Organisms like Tortoise and Banyan Tree are known to have a life span of several years. The organism which has the longest life span has cultural values in many rituals.

Complete answer:
The life span of an organism is simply defined as the period during which it stays alive and dies of natural death. Although in nature death is very uncertain but the period until natural death is called the lifespan of an organism. Life span is affected by various physiological and environmental factors in which an organism lives. Banyan trees have the longest lifespan as compared to any creatures. These trees initiate as epiphytes growing on some other plants. Banyan is considered the national tree of India and is given cultural respect in various aspects.
Banyan trees are widespread, having a very thick bark with fruits called a syconium. Frugivore birds are known to be dispersing agents for Banyan seeds. Banyan trees grow in woodlands when the seed germinates over branches of other trees. The leaves of the banyan trees are large with a glossy green color with a leathery look. With age, the Banyan trees develop aerial prop roots to absorb moisture from the air and to provide support to large structures of the tree. The average lifespan of a Banyan tree is around 200 to 300 years.
A Tortoise has an average lifespan of 80 to 150 years. The average lifespan for parrots is 50 to 70 years. The elephants have a lifespan of around 60 to 70 years.

Therefore, from the above discussion, we can conclude that the right answer is option A.

Note: It is known that a tortoise named Adwaita lived for 255 years. It was a large Aldabra giant tortoise. The human lifespan is very contradictory. Some say it is 1,000 years but surely no human can survive for this long. Much study and investigation are needed to confirm this statement. As of now, the human lifespan is considered around 150 years.
