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