Answer 1

The three essential elements needed for fire to exist are oxygen, fuel, and heat.

Step-by-step explanation:

The three essential elements needed for fire to exist are:

Oxygen: Air contains about 21 percent oxygen, and most fires require at least 16 percent oxygen content to burn. Oxygen supports the chemical processes that occur during fire.

Fuel: Fuel is any kind of combustible material. It's characterized by its moisture content, size, shape, quantity, and arrangement.

Heat: A heat source is responsible for the initial ignition of fire and is needed to maintain the fire and enable it to spread.
