Virus? living or not? if we use the image as an indicator, we might say living because

A virus is a tiny organism and may lead to mild-severe illnesses in animals or plants or humans.

Biologically we can term virus as a bit of RNA or DNA in a protein coat. It cannot replicate without another organism.

If we use an image of indicator, we may say yes virus is living. This is because the virus particle is non-cellular but has an NDA core.This core is enclosed in a protein coat and it has spike-like projections in all over its surface.

Competition. interaction among organisms that compete for the same natural resource (food, shelter, water, space) in an ecosystem. predation. an interaction in which one organism kills another for food. predator. prey. symbiosis. mutualisum. commensalisum. parasitisum.

hope this !
