Dry leaves are an example of which of the following?

Dry leaves are considered a type of tinder because they are small, lightweight, and highly flammable materials that ignite easily. Tinder is often used to start a fire as it catches fire quickly to help ignite larger materials, such as kindling and firewood. Dry leaves, with their low moisture content, are ideal for this purpose, making them effective in fire-starting scenarios.

In contrast, kindling usually refers to slightly larger sticks or twigs that help sustain a flame once it has ignited. Firewood is even larger fuel for a fire and requires more heat to catch fire. A fire igniter typically refers to a tool or substance specifically designed to start fires, such as matches or lighters, rather than organic materials. Thus, calling dry leaves "tinder" accurately captures their function in the process of starting a fire.
