Worked practice questions

A single species showing high diversity across its range illustrates which level?

  1. Genetic diversity
  2. Genuine diversity
  3. Gradual diversity
  4. Granular diversity
Show answer and solution

Correct answer: A. Genetic diversity

1. Diversity is described at three different levels. 2. The narrowest level looks within one species. 3. A single species might show high diversity at the genetic level over its range. 4. So the answer is genetic diversity. _Source: syllabus Biology, Ch 13 'Biodiversity and Conservation'_

The Western Ghats having more amphibians than the Eastern Ghats illustrates:

  1. Sporadic diversity
  2. Species diversity
  3. Spectral diversity
  4. Seasonal diversity
Show answer and solution

Correct answer: B. Species diversity

1. This comparison counts different species, not variation within one. 2. It sits at the middle of the three levels. 3. Diversity at the species level is illustrated by the amphibians of the Western Ghats. 4. So the answer is species diversity. _Source: syllabus Biology, Ch 13 'Biodiversity and Conservation'_

How many major causes of biodiversity loss make up the Evil Quartet?

  1. Four causes
  2. Nine causes
  3. Seven causes
  4. Twelve causes
Show answer and solution

Correct answer: A. Four causes

1. The name of the group is itself a clue to the count. 2. A quartet has a fixed number of members. 3. There are four major causes, described as the Evil Quartet. 4. So the answer is four. _Source: syllabus Biology, Ch 13 'Biodiversity and Conservation'_
