Some people believe fire is alive. It moves it seems to know where to go, it reacts to its environment. Use the 5 characteristics of living things described in lesson 1 and explain what characteristics fire and you have in common and what characteristics it lacks to separate it from you as a living thing.

Answers

well like living things, the fire can grow and develop but in a slightly different manner. Additionally the fire like most living this can move but the fire must have a medium by which it moves (spreading from object to object) as well as, the fire performs gas exchange to some extent as oxygen is needed for burning while carbon dioxide is given off from the fire burning (carbon as a product of combustion).  It can also be argued that like all living things, a fire must die.  However unlike living things, a fire is not made up of cells
