Debido a que las células de los hongos están cubiertos por una pared celular estos no tienen la capacidad de incorporar moléculas grandes y otros organismos sino que deben ingerir su alimento antes de absorberlo este tipo de digestión se denomina A. Intracelular B. Extracelular C. Quimica D. Mecanica

B

Explanation:

Extracellular digestion is a form in which lager molecular food substances are first digested by chemical activities of enzymes and acids  outside the cells,before been absorbed into the body cells.

Fungi are examples of organism with this mode of digestion. They use external source of  energy to breakdown the food substances before digestion.They are called heterotrophic organism because they can not manufacture their food ,but rather depend on external source of energy derived from the organic matter from the  host they feed live on,

The energy sources are the carbohydrates and proteins from the host.
