- 11. QUESTIONS • What is ecosystem ? • Which is the largest ecosystem? • What are the different types of ecosystem? • What are the characteristics of wetland ecosystem ? • Which types of organisms are found in desert ecosystem? • What are the features of grassland ecosystem?
- 12. FOLLOW UP ACTIVITIES 1. Visit and observe any ecosystem nearest in your home and write the features of that ecosystem? 2. Collect the pictures of different ecosystems and prepare an album?
