Saprophytes are fungi that feed on dead and decomposing organisms. They secrete enzymes that digest components of cell walls, such as cellulose and lignin.Which statement explains why these fungi are an important part of the biogeochemical cycle?
A
Saprophytes perform gas exchange that assists the cellular activities or autotrophs
B
Saprophytes extract minerals from living tissue to recycle them back into the soil
C
Saprophytes transport nutrients through the xylem and phloem in autotrophs
D
Saprophytes return organic material to the soil for use by living organisms
Explanation: 

Detailed explanation-1: -Saprophytes are fungi that feed on dead and decomposing organisms. They secrete enzymes that digest components of cell walls, such as cellulose and lignin.

Detailed explanation-2: -Saprophytes are organisms that get their nutrition from dead organic matter, including fallen wood, dead leaves or dead animal bodies. Saprophytes do not usually hurt living organisms. The reason saprophytes are so beneficial to the environment is that they are the primary recyclers of nutrients.

Detailed explanation-3: -Which statement explains why these fungi are an important part of the biogeochemical cycle? Saprophytes return organic material to the soil for use by living organisms.

Detailed explanation-4: -Saprophytes perform gas exchange that assists the cellular activities of autotrophs. Saprophytes extract minerals from living tissue to recycle them back into the soil.

Detailed explanation-5: -Which of the following best describes the role that these microorganisms play in natural habitats? The microorganisms help keep nutrients cycling through the ecosystem. Some species of fungi, protists, and bacteria all play a vital role in every biogeochemical cycle.
