What do fungus gnats feed on?

Explanation:
Fungus gnats feed on fungi that grow in moist, organic-rich potting soil. The larvae live in the soil and nibble on fungal hyphae and spores, which is why damp, plant-filled environments with rich fungal growth support them. Moist soil is about the habitat that lets fungi thrive, not a food source itself. The other options don’t fit because cereals, grains, or decaying wood aren’t the primary foods these larvae rely on in typical home situations, though adults may sip nectar.
