Question

biomass comes from living matter. how is the energy in biomass released for human use? it is turned into water. it is burned. it is crushed. it is frozen, then thawed.

Explanation:

Biomass energy is released when biomass (living matter) is burned. Burning biomass (such as wood, agricultural waste) undergoes combustion. In combustion, chemical energy stored in biomass (from photosynthesis originally) is converted into heat energy. This heat can be used directly (e.g., for heating) or can be used to produce steam to drive turbines (in power plants) to generate electricity. Turning into water, crushing, or freezing - thawing do not release the energy stored in biomass for human use in a useful form like energy (heat or electricity).

Answer:

B. It is burned.
