Which is a possible outcome for future generations of farmers if the same crop is planted on the same patch of land every year? the soil could become infertile due to the lack of time for nutrients to be reinserted

the crops could become resistant to pests and insects through natural selection

the soil could become drought resistant due to the shallow root structure that would form

the crops could begin to change their genetic makeup due to mutations from the parent plants

Tta ttc ctg i hope its right.

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.
