Several traits could lead one to consider viruses as living organisms. They carry and transmit their own genetic information, they consume resources, they move, or rather they take advantage of a host in order to move, and they initiate self-replication when in a suitable host.

Why do scientists debate whether viruses are alive?
Scientists debate whether viruses are alive because they lack the characteristics of traditional living organisms, such as the ability to reproduce on their own. Viruses depend on host cells to replicate and lack cellular structures that define life. Some argue that viruses are on the edge of life, while others consider them more as biological entities.
Which characteristics do viruses possess in common with living cells?
Viruses share similarities with living cells in their ability to reproduce and evolve through genetic mutations. They also contain genetic material, either DNA or RNA, and can infect host cells to carry out their replication. However, viruses lack cellular structures and cannot carry out metabolic processes on their own, which are essential characteristics of living cells.
Why do biologists consider viruses to be nonliving?
Viruses are not cells and do not have a cell membrane or other components of living cells. They cannot reproduce on their own. They cannot move on their own. They also can not use energy. They are alive in the sense that they are organic material, but not in the sense that they are independent living things.Also they cannot respond to stimulus.Most biologists today consider viruses to be nonliving because viruses do not have all the characteristics essential for life. Viruses are not cells and do not use their own energy to grow or to respond to their surroundings. Viruses also cannot make food, take in food, or produce wastes. The only way in which viruses are like organisms is that they are able to multiply.CREDITS FROM: NORTH CAROLINA 8TH GRADE PRENTICE HALL SCIENCE EXPLORER
Why don't viruses have the same structure as the five kingdoms?
Viruses are not considered to belong to any of the five kingdoms of life (animalia, plantae, fungi, protista, and monera) because they lack the characteristics of cells such as organelles, cellular structure, and metabolism. Viruses are considered acellular as they are composed of genetic material (DNA or RNA) surrounded by a protein coat, and they require a host cell to replicate.
Why do people call viruses living when they are not?
While viruses exhibit some characteristics of living organisms, such as evolving and reproducing, they lack key features of life, such as the ability to carry out metabolic processes and respond to their environment. Therefore, they are often considered as biological entities that blur the line between living and non-living.
What has living characteristics but is not alive?
Viruses have some characteristics of life but these are not considered living organisms as they are non cellular.
What is one of the exceptions to a characteristics of life?
One exception to the characteristic of life is viruses. Viruses are considered non-living because they cannot carry out the basic functions of life on their own and require a host cell to replicate.
What characteristics do scientists use to group viruses?
Viruses can be grouped by their shape, the type of disease they cause, their life cycle, or the kind of genetic material they contain. And, the four main shapes of viruses are: Crystals, Spheres, Cylinders, and Spacecraft.
What are characteristics of viruses?
viruses are obligate intracellular entities and are considered to be acellular
What characteristics of a virus?
Viruses multiply within the host cells and give rise to the same genetic types. Viruses show extremely specific intracellular parasitism. They can easily be crystallized and precipitated. Viruses have no cytoplasm,nucleus,membranes,ribosomes,enzymes etc.
What do you call an organism that does not show any signs of life?
yes dead is the more obvious answer but also you could say something hibernating shows very little signs of life But then there are also viruses and prions that show no signs of life at all unless they are attached to a protein or another cell
Where are viruses on the tree of life?
Many, if not most biologists do not consider viruses living. So, they are not on any phylogenetic tree that I know of. They may have a phylogeny that I am unaware of, though.
Why do scientists debate whether viruses are alive?

You know viruses are not alive because?
viruses do not have the ability to replicate on their own or carry out metabolic functions like living organisms do. They require a host cell to reproduce and do not possess the machinery needed to do so independently.
Are diseases abiotic?
A disease can be biotic or abiotic. If it is a bacteria it is biotic, but if it is a virus it is always abiotic, because viruses are not considered living because they cannot reproduce on there own, do not consume energy or give off waist.
What are the characteristics used to classify viruses?
size and shape
What characteristics do scientists use to classify viruses?
their genome
