It is difficult to classify viruses as living organisms because they are not made of cells. They only become alive when they find a host i.e. a living cell to live in.
Viruses lack the characteristics of living organisms, such as cellular structure and metabolism, making it challenging to classify them within the traditional system of biological classification. Additionally, viruses are considered obligate intracellular parasites that can only replicate inside host cells, further complicating their classification within the existing kingdom system.
The domain Prokarya consists of the kingdoms Bacteria, Archaea, Viruses, and viroids. Bacteria and Archaea are single-celled organisms with prokaryotic cells, while viruses and viroids are acellular infectious particles. Bacteria are diverse and found in various environments, while Archaea are often extremophiles. Viruses and viroids are not considered living organisms and require a host for replication.
Viruses are not considered to be part of any of the traditional biological kingdoms (Animalia, Plantae, Fungi, etc.). They are typically classified in a separate group known as the kingdom Viruses or under domain as Obligate Intracellular Parasites.
Viruses do not belong to any of the five kingdoms of life.
The five kingdoms for microorganisms are Bacteria, Archaea, Protista, Fungi, and Viruses. Each kingdom represents a different group of microorganisms with distinct characteristics and biological functions.
Viruses are classified differently than living organisms, since they are not technically alive. In taxonomy, viruses are not assigned to a Domain, Kingdom, Phylum, Class, or Order. The influenza viruses start, in most classification systems, at the level of the Family. They are in the Family of Orthomyxoviridae. There are a few newer classification systems that have been developed to better categorize and classify viruses, but these are not yet the standard.
It is because viruses are not made up of cells
lichens, corals, viruses, corals, viruses and carnivourous plants are difficult to classify :)
Living. Because viruses are caused by germs...which are living organisms
It is difficult because viruses lack the ability to replicate themselves and theey lacks energy metabolism and other pathways that living things have. Viruses are totally depending on their host. If they want to replicate, they have to infect the host.
Prokaryotic (has a nucleus) and eukaryotic (no nucleus).
Viruses can be labeled as RNA or DNA viruses and they can be said to have an envelope or to be "naked".

Viruses are not considered to be part of any of the traditional biological kingdoms (Animalia, Plantae, Fungi, etc.). They are typically classified in a separate group known as the kingdom Viruses or under domain as Obligate Intracellular Parasites.
Viruses need living cells to produce more viruses. They are obliged to use living cells.
viruses are unicellular organisms
