What is biomass?

Biomass refers to organic material derived from living or recently living organisms, primarily plants and animals. This material can be used as a renewable energy source because it can be converted into various forms of energy, such as biofuels, biogas, and electricity. Biomass is considered a sustainable energy option as it can help to reduce reliance on fossil fuels, decrease greenhouse gas emissions, and minimize waste by repurposing materials that would otherwise be discarded.

The focus on organic material is crucial in distinguishing biomass from other types of fuel sources such as fossil fuels, which are derived from ancient organic matter that has undergone significant geological changes over millions of years. This distinction highlights why the correct answer is that biomass is organic material that can be used as energy.
