Question

Choose the correct statement by observing the given image.

  1. The forest will not abruptly give way to a grassland's wide-open areas
  2. Long portions of this zone can be found crossing three different ecosystems, and it is here that all ecosystems' characteristics can be observed.
  3. Elephants prefer to break up the forest by stomping when they move, turning the area into a grassland along their path
  4. Elephants do not repeatedly take the same route (creating elephant corridors)

hintHint:

The elephants prefer to break up the forest by stomping when they move, turning the area into grassland along their path.

The correct answer is: Elephants prefer to break up the forest by stomping when they move, turning the area into a grassland along their path


    • Ecological succession occurs by some biotic factors.
    • Elephants are one of those factors that convert the forest ecosystem into a grassland ecosystem.
    • The elephants break the trees and shrubs by moving when they are in search of food.
