Detailed explanation-1: -Host-a living thing that provides a source of energy for a virus or an organism.
Detailed explanation-2: -A virus is an infectious agent that can only replicate within a host organism. Viruses can infect a variety of living organisms, including bacteria, plants, and animals.
Detailed explanation-3: -How do viruses enter the body? Viruses are unable to reproduce by themselves. In fact, they barely qualify as living things when outside of a host. But these parasites are well designed to infiltrate host cells and replicate copiously.
Detailed explanation-4: -Viruses cannot generate or store energy in the form of adenosine triphosphate (ATP), but have to derive their energy, and all other metabolic functions, from the host cell. They also parasitize the cell for basic building materials, such as amino acids, nucleotides, and lipids (fats).
