The role of producers in a food web are very important, it’s the the most important part of the food web it’s the main food source that has energy from the sun, plants use the sun for photosynthesis to make food which helps them continue to grow and can feed off for other animals or plants

Producers are the beginning of a simple food chain. ... All energy comes from the Sun and plants are the ones who make food with that energy. They use the process of photosynthesis. Plants also make loads of other nutrients for other organisms to eat.

ribosome

Explanation:

Viruses are the microorganisms which harmful for human health. They require a host body for replication and their replication in the body of host cell causes infection or disease.

There are several important structures present in virus that support the replication of virus such envelope, capsid and DNA. Envelope is the outer covering of virus that help to restrict the action of host's immune system, capsid have several function in viral replication such as nucleic acid protection form enzymes, provide protein for penetration into host cell and provide sites on its surface to attach host cell and DNA carries the genetic material that is must to carry same viral genes to other generation.

Ribosome has the least effect on the virus replication because some of the viruses lack ribosome and they can use ribosome of host cell to translate viral protein.  

Hence, the correct option is ribosome.
