A virus is a simple organism, I think the large molecules inside are considered complex elements.
always was bad at science but ill give it a shot think of it like a baby is a simple organism but the process and all the neccessary things needed to make that one baby are the complex elements you cant make one without "complex elements" hope that helps :/
a simple organism can be defined as a bacteria cell which contains a nucleus, electron, and proton......
