Observe two different places near your home or school (e.g., a park and a roadside). Class 8
Question 1.
Observe two different places near your home or school (e.g., a park and a roadside). List the living and non-living components you see. How are the two ecosystems different? Class 8
Answer:
Comparing a park and a roadside :
| Component | Park | Roadside |
| Living | Trees, birds, squirrels, insects, grass | Few plants (weeds), stray animals, insects |
| Non-living | Soil, water, sunlight, benches | Dust, cement, noise |
Difference :
- Park has a designed ecosystem with diverse plants and animals.
- Roadside is a disturbed, human-altered area with fewer species and more pollution, less biodiversity.
Question 2.
‘Human-made ecosystems like agri-cultural fields are necessary, but they must be made sustainable.’ Comment on the statement. Class 8
Answer:
- Agree. Agricultural fields give us food, but overuse of synthetic fertilisers harms nature.
- Sustainable farming (such as organic farming, crop rotation) protects soil, water, and biodiversity for future generations.
