What would happen if pesticides drastically reduced the number of caterpillars in the food chain?

Sun --> Fig --> Caterpillar --> Lizard --> Eagle

• The lizard population would adapt to eating the strangler fig

• The fig population would increase; the lizard population would decrease

• The lizard population would remain the same; the strangler fig population would decrease

• The fig population would be unaffected; the lizard population would increase
