Saprophytes are fungi that feed on dead and decomposing organisms. They secrete enzymes that digest components of cell walls such as cullulose and lignin

The most appropriate answer option is: D) Saprophytes return organic material to the soil for use by living organisms.

Explanation:

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.

the sun d the answer is sun

1. a host loses nutrients to a parasite

2. a parasite only benefits when the host is alive (cause if the host dies the parasite dies with it )

3. producers to consumers

4. the tapeworm is a parasite

5. they convert energy from the sun (photosynthesis)

6. sunflower-robin (i think im 80% sure)
