Class 7 students should be able to understand what words like “ecosystem” and “biodiversity” actually mean. This video explains what they are and how the same type of ecosystem in different parts of the world has different species and why this diversity needs to be conserved.
Suggested questions for classroom discussion based on the video:
- Are there same types of ecosystems in different parts of India? How are they different? What are the different species found in both the ecosystems?
- Are ecosystems dependent on each other? Why must we conserve different types of ecosystems?
- What is the importance of conserving ecosystems? What effect would it have on us?
- Look at different types of ecosystems in India – what would be the possible consequences if they were destroyed? How would this directly affect both people and animals dependent on those ecosystems?
