Because almost all viruses need a host in order to survive. Without a host, they wouldn't be able to reproduce and spread.
All three domains of life—Bacteria, Archaea, and Eukarya—share the characteristic of being composed of cells, which are the basic units of life. Additionally, viruses, although not classified as living organisms, possess genetic material (DNA or RNA) and can evolve, similar to cellular organisms. This shared feature of genetic material underscores the fundamental biological processes of replication and evolution across all domains and viruses.
Cells are the fundamental unit of life.
The basic units of life are cells. Cells are the smallest structural and functional unit of an organism, and they can perform all necessary functions for life, such as growth, metabolism, and reproduction. All living organisms are composed of one or more cells.
A mass of protoplasm is typically called a cell. Cells are the fundamental units of life and contain various organelles that perform specific functions within the cell.
The statement "All tissue is made up of tiny units" is known as the Cell Theory. It states that all living organisms are composed of cells, which are the fundamental units of structure and function in living organisms.
Living organisms are composed of cells, which are the fundamental units of life. Cells contain genetic material, organelles, and molecules that work together to carry out the functions necessary for life. Each cell is specialized to perform specific roles in the organism.

Viruses are considered non-living because they cannot carry out essential life processes on their own, such as metabolizing nutrients or replicating. They require a host cell to replicate and do not have the ability to grow or respond to stimuli independently.

Cells are the fundamental unit of life.
Since viruses are not alive they can not have life processes.

get a life they arent
Yes. DNA is the fundamental blueprint for all life on Earth.That depends on your definition of Life.Are viruses alive? Some say yes and some say no. Some viruses have DNA, and some only have RNA. So if you consider viruses a form of life, then some do not have DNA. RNA virus examples are SARS and Hepatitis. If you don't consider viruses alive, then yes, all forms of life (that we know of) higher than a virus contains some form of DNA. You can find out more at the link below.
there are 2 different units of life
A mass of protoplasm is typically called a cell. Cells are the fundamental units of life and contain various organelles that perform specific functions within the cell.
