A
Increased browsing by the herbivores stimulates the plant growth leading to increased primary productivity
B
Overgrowth of herbivore population causing reduction in tree populations and therefore, if the process continues the entire ecosystem will breakdown
C

D
Overgrowth of herbivore population without any change in the remaining part of the ecosystem
