Primary consumers eat producers. So, in a food web, primary consumers have arrows pointing to them from producers.
The bolete fungus has arrows pointing to it from the black racer, the gray fox, and the bobcat. None of these organisms is a producer, so the bolete fungus is not a primary consumer.
The black bear has an arrow pointing to it from the persimmon tree. The persimmon tree is a producer, so the black bear is a primary consumer.
The silver maple does not have any arrows pointing to it. So, the silver maple is not a primary consumer.
The pine vole has an arrow pointing to it from the persimmon tree. The persimmon tree is a producer, so the pine vole is a primary consumer.
The parasol fungus has arrows pointing to it from the pine vole and the black bear. Neither the pine vole nor the black bear is a producer, so the parasol fungus is not a primary consumer.
