If the biomass of flowers that support the butterflies the same grassy meadow was known to contain 100,000 units of energy, and certain bird species were eating the butterflies that foraged on the flowers, what amount of energy, on average, could be expected to be transferred to the birds?

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.
