Biomass is any organic matter that can be used as an energy source. Wood, crops, and yard and animal waste are examples of biomass.People have used biomass longer than any other energy source. For thousands of years, people have burned wood to heat their homes and cook their food.Biomass gets its energy from the sun.Plants absorb sunlight in a process called photosynthesis.iomass is any organic matter that can be used as an energy source. Wood, crops, and yard and animal waste are examples of biomass.
Biomass is an important piece of information that ecologists use to better understand ecosystems. They can compare biomass to productivity and see how energy is transferred between different trophic levels.iomass is an important piece of information that ecologists use to better understand ecosystems.
