Multiple choice

The side effect(s) of heavy and constant grazing is/are that the

  1. upper layers of soil are loosened and are eroded

  2. lower layers are made more compact and root respiration is interfered with

  3. lower compact layers make root penetration difficult

  4. All of the above

D Correct answer
Explanation

Heavy grazing affects soil at multiple levels: it loosens and exposes upper soil layers to erosion (option A), compacts lower layers making them impermeable and hard for roots (option B), and these compacted layers prevent proper root penetration (option C). Since all three effects occur simultaneously due to heavy grazing, option D 'All of the above' is the correct answer.
