The relationship between frog and insect is as follow:
Predatory-prey relationship is found between the frog and the insects. In the food chain, the frog is a predator and the insects is a prey.
If the number of frogs decreased because of human activity, then the possibility is:
- The number of insects might increase if the number of frogs decrease because the insects are the primary food of frogs.
- So if the number of frog decrease, the population of insects would increase as there is no predator.
Thus, the frog and insect share a predatory-prey relationship.
