Which sentence describes energy flow through a natural (not manufactured) system?

A strong wind blows across a Midwestern prairie. The wind forces the blades of a wind turbine to rotate. As the blades spin, the turbine converts mechanical energy to electrical energy. The electricity generated by the wind turbine is used to power nearby homes.

The correct option is this: A STRONG WIND BLOW ACROSS A MIDWESTERN PRAIRIE.

A strong wind is an example of a natural force. The prairie refers to a land fill with grasses and that is a natural factor also. Thus, a strong wind that is blowing across a prairie is generating a natural form of energy. The energy flow in the other options given are examples of man made devices.
