Answer:
Sugarcane.
Explanation:
Biomass is renewable energy from plants and animals so we cross out everything that isn't a plant or animal and you get sugarcane left.
Yes biomass holds the suns energy but it's not the energy source exactly. It gets the energy from the sun because plants go through photosynthesis and absorb sunlight.
So the main source is sugarcane since it's a plant that makes it's own energy as well as taking energy from the sun.
Hope this helps. :)
