Quick oral answer
Cropland is an artificial or human-made ecosystem because it is created, planted, and maintained by humans for growing crops, unlike forests or ponds which develop naturally.
Common mistakes
- 1.Students sometimes confuse ponds or grasslands as artificial, but they are natural ecosystems.
- 2.Not distinguishing between natural habitats and human-managed agricultural fields.
Analysis and explanation
According to the NCERT text, ecosystems can be natural or human-made (artificial). Forests, ponds, and lakes are examples of natural ecosystems because they exist and function naturally without human intervention. In contrast, gardens and crop-fields (croplands) are created and managed by humans, making them human-made or artificial ecosystems. Therefore, a cropland ecosystem is not a natural ecosystem.
Interesting facts
Crop-fields are highly simplified ecosystems with very low species diversity compared to natural forests, making them highly vulnerable to pests and dependent on human inputs like fertilizers.
