Multiple Choice

Is biomass energy a renewable energy source?

• Yes, always, because you can grow trees again.

• No, it's just like fossil fuels.

• It depends, only if the source is not overharvested.

• No, because manure is not renewable.

Multiple Choice

What is biomass energy?

• any organic matter that can be used by burning wood and other plant life.

• Radiant energy emitted by the sun.

• a combustible black or dark brown rock consisting mainly of carbonized plant matter, found mainly in underground deposits and widely used as fuel.

• made by tapping into steam or hot water reservoirs underground; the heat is used to drive an electrical generator.
