Answer 1

Viruses can use energy of living cells that they infect

Viruses can replicate inside a host that they infect this is the reason why viruses do not have special structure or enzymes that allows them to make their own food. They just replicate and infect but they never make their own food.

Viruses depend on the host cells that they affect to reproduce. When found outside of host cells, viruses live as a protein coat or capsid, sometimes contained within a membrane. The capsid surrounds either DNA or RNA which codes for the virus elements.
