Answer
Food chain in a cabbage farm:
Cabbage → Rabbit → Snake → Hawk
Pesticides are non-biodegradable and persist in the ecosystem. When humans eat plants or animals that fed on those plants, the pesticide enters the food chain and accumulates at each trophic level. Hence, the last trophic level (humans) gets the highest concentration of pesticide — a process called biological magnification which leads to adverse effects on human health.
