प्रश्न
What would happen if an organism is removed from the food chain?
उत्तर
If an organism is removed from the food chain,
- The food chain will fall apart.
- The ecosystem will become imbalanced and collapse.
- For example, Consider a food chain: Plants → grasshoppers → frogs → snakes → hawks.
If frogs were to die off in this chain, (due to disease/pollutants), then, there will be an increase in the number of grasshoppers. This will cause a major problem.
