Final answer:
Option (d), Fungi secrete digestive enzymes into their environment, which breaks down organic material allowing them to absorb nutrients.
Step-by-step explanation:
Fungi release digestive enzymes into their environment. These organisms are renowned for their essential role as decomposers. They secrete exoenzymes or digestive enzymes outside of their cells to break down large, complex organic materials into smaller, absorbable molecules.
This external digestion process is fundamental for the fungi to absorb nutrients and recycle carbon and inorganic minerals through the decomposition of dead organic matter.
