D) Saprophytes return organic material to the soil for use by living organisms
Saprophytes are organisms that feed on organic matter originating from decomposition processes. They are heterotrophic because they obtain energy from organic matter in other living beings.
The main saprophytic living beings are terrestrial fungi and some species of vascular plants. They are essential for biogeochemical cycles, because they return organic material to the soil for use by living organisms.
In other words, we can say that saprophytes act as nutrient recyclers. They act in the process of decomposition of the substrate (place where they live), favoring the use of substances by other organisms. This process also favors soil fertilization.
Example: there are fungi that decompose rotting tree branches and stumps. The result of this process generates organic substances that serve as nutrients for other organisms in that ecosystem.
The answer would be D
This is true because one of the main things for fungi to do is breaking down materials, when they break materials down it is easier for them to mix in with the ground around them there fore causing them to be returned.
The most appropriate answer option is: D) Saprophytes return organic material to the soil for use by living organisms.
A saprophyte, also known as a saprobe or saprotroph, is an organism (fungi) which feeds and grows on decomposing organisms. We also know that it secrete enzymes that digest components of cell walls, such as cellulose and lignin.
Saprophyte is an important part of the biogeochemical cycle as it decomposes the bodies of the dead organisms, recycles them and releases nutrients into the soil to be used by the living organisms.
