What's the same about biotic and abiotic factors

 -Both can be potentially harmful/ disease-causing
-Both are necessary for organisms to survive
-Biotic factors can affect abiotic factors, and likewise, Abiotic factors can affect Biotic factors

They are both factors that affect the environment

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.
