A) producers
B) biomass
C) solar energy
D) grassland
Correct Answer: C
Solution :

Only 10% of the energy is transferred from one trophic level to the next trophic level and rest of the energy is used up in biological activity and gets wasted in the environment.You need to login to perform this action.
