Question

Describe how human intervention with a community can interfere with normal predation, and give two examples.

Answer 1

1. Human intervention in a community can interfere with normal predation by disrupting natural predator-prey relationships, often by removing or adding species artificially. It can cause imbalances such as overpopulation of prey or decline of predators.
2. For example, hunting big predators reduces predation, leading to overgrazing by herbivores, and introducing invasive species can alter predation patterns.
3. Another example is habitat destruction, which removes predator habitats, thus interfering with standard predatory control.
4. Two examples of human interference in predation are uncontrolled hunting of big predators and introducing invasive species; in competition, examples include habitat destruction and artificial feeding of particular species.
