प्रश्न
Why are crop fields known as artificial ecosystems?
उत्तर
Artificial ecosystems are ecosystems which are created or maintained by humans. Crop fields are an example of artificial ecosystems because plants grown in fields are selected by humans. Also, humans add chemicals such as manure, pesticides or herbicides in the fields to increase soil nutrients or control the organisms. Since humans manipulate both biotic and abiotic components of the crop fields, these are known as artificial ecosystems.
