Corn, as this is what the biomass ethanol is made of. Research is pointing to algae becoming the next great biomass however, because of the substance's ability to produce oil.

In a developing country, biomass is most likely to be used for cooking and heating purposes. This can involve burning wood, crop residues, animal dung, or charcoal for energy. Biomass is often a primary energy source in areas with limited access to modern fuels and technologies.
Biomass energy can be used as electricity, fuel and many more

Biomass naturally occurs in nature as plants and animals degrade. It can be anything from fallen over logs to your plant trimmings. In biomass utilization all materials that can be found are used. Although sometimes slash and burn methods are used in forests to get the biomass material. Biomass utilization is the number one renewable resource used in the world even though it still cause's damage to the atmosphere and prevents plants longevity of live by depleting the future nutrients of the soil.
Oil, is the most commonly used non renewable resource.
Biomass energy is widely used. One state that uses biomass is Oregon.

Halite is one of the most used items. It is rock salt often used on roads in winter to melt snow and ice.
Biomass is material derived from living organisms. The term biomass for energy is often used to refer to plant based materials, but it can equally apply to animal, as well as vegetable matter--the key is 'living organisms'. So no, biomass engergy does not ONLY come from plants.
