The arrow definitely points to a producer so right away that means the answer will probably be either A or B.

C is plainly silly - consumers don't recycle nutrients like glucose, they burn them up. And D is also silly - producers feed consumers, not the other way around.

Plus neither C nor D has any relationship to the organisms the arrow points to.

B is also out. Producers bring energy into the ecosystem, but they don't break down complex organic molecules and turn them into new ones. As discussed in the last question, that is what decomposers do.

So by process of elimination, that leaves...?
