Answer:
I think D (This isn't verified as correct, only my best concluded answer in terms of correction.)
Explanation:
The reason why I believe D is the answer is because the other answers are included in a food web. The reason for considering D is because I'm pretty sure that consumers are apart of a food web which could be logical for eliminating answer B. D would be a good answer considering that a food web consists of producerd and consumers and the transfer of energy. Relative to whether that's considered as a predator prey relationship other than an energy transfer relationship then D would probably be your answer.
