Solution and Explanation
Roles of predation:
Maintains species diversity: Predators control the population of prey, preventing any single species from dominating. Example: Lions preying on zebras in savannahs.
Regulates ecosystem balance: Predators ensure a balance between herbivores and plants. Example: Wolves controlling deer populations.
Promotes natural selection: Predation exerts pressure on prey to evolve defensive mechanisms. Example: Camouflage in stick insects.
