Do viruses need energy

Every living organism has to have energy to move. So i guess that viruses do need energy to move about. Hope this helped! :)

Viruses float in the air until they come in contact with a host cell. The virus must invade the cell to get the energy it needs to reproduce. So yeah, they need energy, but not to live... to reproduce.

True statement gravity force is more on bigger mass, less on smaller mass.all mass fall on planet with same acceleration and speeds

The answer is atmosphere. there are four spheres of the earth: 1. geosphere (from greek word 'geo' = ground), 2. hydrosphere (from greek word 'hydro' = water), 3. biosphere (from greek word 'bio' = life), and 4. atmosphere (from greek word 'atmo' = air). a magnetosphere is a region of space around astronomical objects controlled by the magnetic field of that object. through the process of elimination, since lightning is present in the air, it can be found in the atmosphere.
