Step 1: Understanding the Concept
Ecosystem diversity means the variety of ecosystems, such as forests, deserts and wetlands, in a region.
Step 2: Statement I
India has deserts, rain forests, mangroves, coral reefs, wetlands and alpine meadows, so its ecosystem diversity is far greater than that of Norway. The statement is incorrect.

The Western Ghats have many ecosystems, while Ladakh (cold desert) and the Rann of Kutch (salt marsh) are comparatively uniform. The statement is correct.
Final Answer:
