Try it on paper first. A hint, the key idea and the worked solution are here when you need them.

For each case, say whether it is genetic diversity, species diversity or ecological diversity.

India has more than $50,000$ strains of rice.

The Western Ghats have more kinds of frogs than the Eastern Ghats.

A country has a desert, a mangrove, a coral reef and an alpine meadow.

Rauwolfia vomitoria from different Himalayan ranges has different amounts of reserpine.

A farmer grows $12$ varieties of mango in one orchard.

Need a reminder? The key ideaShow

Genetic diversity is the variety inside one species. Species diversity is the variety of species in a region. Ecological diversity is the variety of ecosystems. Simpson's index of diversity is $D = 1 - \sum (n/N)^2$ , where $n$ is the count of one species and $N$ is the count of all (not in the NEET syllabus).

The worked solution

Have you tried it?

Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
