Energy exists in different forms:
Thermal energy, electrical energy,
Magnetic energy, chemical energy,
Wind energy, solar energy and et al.
Bio-energy consists of chemical,
Thermal, electric, magnetic energy.
Bio-energy confines to bodies
And is distinct from their counterparts
That exist outside the living bodies
In that it as a unit cannot exist
Without the living mass in any way,
That it ceases when bodies disintegrate,
And that it transmits through reproduction.
Bio-energy is only expandable.
