How do keystone species illustrate the interdependence of organisms living in a community?

Without the keystone species, the next top predator will be the top of the food chain with no predator. This new top predator will, therefore, become over populated and as a result, eat too much of whatever its prey is, creating an extremely fragile and unbalanced ecosystem

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.
