What would happen if people killed the predator in food chain?

If humans killed all the predators in a food chain, the ecosystem would be severely disrupted. Without predators, the population of prey species would increase rapidly, leading to overpopulation and competition for resources. This would eventually result in a crash in the prey population, as they would exceed the carrying capacity of the environment and deplete their food supply.

The loss of predators would also have a negative impact on other organisms in the food chain. For example, plants that rely on predators to control herbivore populations would be overgrazed, leading to deforestation and soil erosion. Additionally, the loss of predators would disrupt the flow of energy and nutrients through the ecosystem, affecting the entire web of life.

In short, killing all the predators in a food chain would have devastating consequences for the ecosystem, leading to population imbalances, resource depletion, and widespread environmental degradation.
