Answer: 1, 2 and 3
Notes: The grazing food chain's primary source of energy is indeed living plant biomass and in the detritus food chain, the source of energy is dead organic matter or detritus. Also, it is factual that waste materials and dead organic matter from the grazing food chain serve as the initial energy source for the detritus food chain. However, the fourth statement is incorrect. The grazing food chain and detritus food chain although distinct in their function, they do interact and are interconnected in nature, forming a complex ecosystem.
