For each case, say whether it is genetic diversity, species diversity or ecological diversity.
- India has more than 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 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 , where is the count of one species and 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.
Step 1. (a) All the strains are of one species. Genetic diversity.
Step 2. (b) The cases are different species of frogs in two regions. Species diversity.
Step 3. (c) A desert, a mangrove, a reef and a meadow are different ecosystems. Ecological diversity.
Step 4. (d) The plants are of one species, and they differ in the potency and amount of the chemical. Genetic diversity.
Step 5. (e) The varieties of mango are of one species. Genetic diversity.
Answer: (a) genetic; (b) species; (c) ecological; (d) genetic; (e) genetic.
Watch out. Many strains or varieties do not make species diversity. The test is whether they are one species or many.
