Which of the following is an example of a living organism?

A lightning bolt
A rock
A tree
The Sun

The correct answer is: A tree

A lightning bolt is a powerful electrical discharge, not a living organism. It does not grow, reproduce, or respond to its environment like living organisms do. A rock is an inanimate object and does not exhibit any characteristics of living organisms. It does not require energy, grow, or reproduce. The Sun is a star and is not considered a living organism. It does not consume or use energy in the same way living organisms do. It also does not exhibit any characteristics of living things such as growth or reproduction. A tree is a living organism as it grows, reproduces, and responds to its environment in order to survive. It requires energy from the sun and is able to convert it into food through photosynthesis. Therefore, C is the correct answer.
