| 3. What role do humans play in the web of life? | |
Ans. Humans play a significant role in the web of life. Our activities, such as farming, building, and pollution, can impact the environment and disrupt the balance of ecosystems. However, we can also help protect the web of life by conserving nature and promoting biodiversity.
