Viruses do not really "eat" because they are not alive. They are called microbes and microscopic organisms by some scientists for ease of discussion, but they don't meet the strict definitions of these, so other scientists prefer to call them "sub-microscopic infectious agents".
They carry pieces of DNA or RNA and attach to and enter a living host's cells (plant or animal) and cause those cells to create more viruses. The virus causes this replication by modifying the DNA of the "invaded" host cells to make them stop their original function in the host and turn into a cell functioning only to reproduce copies of the virus. The material and energy needed to reproduce them is not coming from the virus or to the virus in the form of food, it is provided by the host animal's or plant's cells. Viruses can not continue to replicate (stay "alive") without the host cell doing the work and providing the materials.
What else can I help you with?
How are viruses similar to living organisms and how are they different?
Viruses are similar to living organisms because both contain hereditary material (RNA or DNA), and both reproduce. Viruses are different from living organisms because they do not use energy to grow, and do not use energy to respond to their surroundings.
Do viruses come in many shapes and sizes?
yes but a lot of viruses are copies of themselves
What do flies drink to sustain themselves?
Flies sustain themselves by drinking liquids such as water, nectar, and other sugary substances. They also feed on decaying organic matter for nutrients.
WHY do viruses reproduce in the living cell?
to divide themselves
Can viruses can reproduce by themselves?
No. Viruses must invade a host cell and hijack its resources to replicate itself.
Can viruses reproduce by themselves?
No. Viruses must invade a host cell and hijack its resources to replicate itself.
How did Greeks during this time period sustain themselves economically?
DHS :)
Can viruses infect plants by themselves?
Yes, viruses can infect plants by themselves. Plant viruses can be transmitted by insects, through contaminated soil, or by mechanical means like pruning tools. Once inside a plant, viruses can replicate and spread throughout the plant's tissues, causing disease symptoms.
What do butterflies eat to sustain themselves?
Butterflies sustain themselves by feeding on nectar from flowers. They also consume other liquids like tree sap, rotting fruit, and even animal droppings for essential nutrients.
How do eagles stay alive?
Eagles nurture themselves to stay alive. They also drink enough water to sustain themselves.
Why do viruses replicate?
Viruses replicate to produce more copies of themselves and spread to new host cells or individuals. This replication process is crucial for the survival and propagation of viruses in their environment.
What can viruses attach themselves to?
Viruses can attach themselves to host cells, bacteria, fungi, and other viruses for the purpose of infecting and replicating within these organisms. They require a specific receptor on the surface of the target cell to bind and gain entry for their replication process.
