- 1. Multiple ChoiceWhich is NOT an example of biomass?woodcrop leftovers (the part of the plant that isn't consumed)manure and/or trashpetroleum
- 2. Multiple ChoiceWhich type of fuel produces the most sulfur?windcoalbiomassnuclear fission
- 3. Multiple ChoiceHow does biomass reduce our carbon footprint by producing less CO2 than fossil fuels?Plants absorb the same amount of CO2 that is released when it is burned.Plants remove CO2 from the atmosphere and put it permanently into the ground.Biomass filters CO2 to make it more environmentally stable.Biomass doesn't release any CO2 when burned.
