What is biomass energy?

the chemical energy stored in living things
the electromagnetic energy stored in living things
the nuclear energy stored in living things
the thermal energy stored in living things

Not sure what this one could be

Since this is not my area of expertise, I searched Google under the key words "biomass energy" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.

Biomass energy refers to the energy that is derived from organic matter, such as plants or animal waste. It is a renewable source of energy because it is derived from living or recently living organisms. The correct option among the given choices is "the thermal energy stored in living things."

To arrive at this answer, let's examine the other options:
- The chemical energy stored in living things: This refers to the energy stored in the chemical bonds of molecules within living organisms, but it doesn't specifically relate to biomass energy. Therefore, this is not the correct choice.
- The electromagnetic energy stored in living things: While sunlight is an important energy source for biomass production through photosynthesis, the energy stored in living things is primarily in the form of chemical or thermal energy, not electromagnetic energy. So, this option is not the correct choice.
- The nuclear energy stored in living things: Nuclear energy involves the release of energy from the nucleus of an atom, which is not applicable to the context of biomass energy. Therefore, this is not the correct choice.

Considering these explanations, the correct answer is "the thermal energy stored in living things."
