The constant grazing and browsing, in an area, may utilimately result in the formation of
Options
(a) desert
(b) dense forests
(c) grassland
(d) bushy vegetation
Correct Answer:
desert
Explanation:
When natural grasslands become pasture, the native grazers are replaced by the domestic kind : cattle, horses, sheep and goats. Since grasslands are adapted to heavy energy flow along the grazing food chain, such a switch is ecologically sound. However, humans persistently suffer from the tragedy of the commons by allowing overgrazing and overplowing. Many grasslands, therefore,now human-made deserts that are difficult to restore to the grassland state.
