Grass-->Beetle-->Frog-->Snake-->Hawk. Given the following food chain, describe what would happen if the species in Trophic Level 3 went extinct?
The snake and hawk populations would die/decrease, and the beetle population would increase. The increase in the beetle population would eventually cause a decline in the grass population.
