Fungi obtain nutrients by external digestion
a. true
b. false

True.

Explanation:

The fungi are eukaryotes, single or multicellular, all heterotrophs. Although some species may have greenish coloration, the fungi do not have chlorophyll or any other photosynthetic pigment. Thus, they need organic matter to survive. They get the nutrients they need through direct absorption (when these molecules are available in their environment) or by secreting digestive enzymes around them to break down the macromolecules of their organic food; subsequently the resulting nutrients are absorbed. In summary, they usually perform extracellular digestion of food and then absorption of nutrients.
