Ascientist found a new bacteria in a hot water sulfur spring that uses sulfur
as a source of energy instead sunlight. what kind of organism could it be?

This could be in the kingdom Archaea, also known as extremists as far as environmental conditions are concerned :)

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.

We can use solar powered cars or ride bikes instead of cars that burn fossil fuels
