alleryPredators such as lions and tigers are considered important in an ecosystem mainly because they:
AIncrease the number of herbivores
BDecompose dead plant material
CProduce food by photosynthesis
DPrevent overpopulation of herbivores
Answer & Solution
Correct answer: D. Prevent overpopulation of herbivores
1. Producers make food and decomposers break down waste, but predators do neither.
2. Predators feed on herbivores and keep their numbers in check.
3. This prevents overpopulation of herbivores, maintaining balance.
4. So the correct role is preventing overpopulation of herbivores; increasing their number is the opposite, so it is wrong.
