What is fuel loading? What are examples of fuel loading, and what makes fuel combustible?
What will be an ideal response?
ANSWER: Fuel loading refers to the amount of burnable material. Trees and dry vegetation are the primary sources of fuel for a wildfire. They burn at high temperature by reaction with oxygen in the air. The main combustible part of wood is cellulose, a compound of carbon, hydrogen, and oxygen. When it burns, cellulose breaks down to carbon dioxide, water, and heat. Shrubs and trees also contain natural oils or saps that add to the combustibles.
