Question

multiple - choice question
how do we get energy from biomass?
letting it decay and warm up
burning it
processing it into liquid fuel

Explanation:

Biomass energy can be obtained through multiple methods. Burning biomass releases energy directly. Biomass can also be processed into liquid fuels like bio - diesel for energy use. While letting biomass decay can produce biogas (a form of energy) over time, the description "letting it decay and warm up" is a rather simplistic way of referring to anaerobic digestion which is a more complex process for energy extraction. All the given options are valid ways to get energy from biomass.

Answer:

A. letting it decay and warm up
B. burning it
C. processing it into liquid fuel
