Food chains and webs not only describe the order organisms are eaten, but they also describe the flow of energy in an ecosystem. We and all things are made of energy, so the way that energy change forms and pass from one thing to another is one way to describe an ecosystem, and more in general it is a correct way to explain how life on Earth works.
Answer:
They can use the host cell to copy themselves and make viral proteins
Explanation:
Viruses are organisms that are incapable of replicating on their own without infecting a living host. They use the host's ability to transcribe, translate and replicate to replicate themselves and translate their genetic material into proteins. The infection cycle represents their reproductive cycle.
Viruses infect their host cell by initially binding to specific receptors on the host's cell membrane. Then, they enter the host cell and incorporate their genetic material into the host's genome. They, then, use the replicational ability of their host to produce many virions and make proteins.
