What to expect: This mock test covers key concepts from the Biodiversity and Conservation chapter — including application-based and competency-focused questions aligned with how ICSE actually sets the paper.
Tip: Attempt without notes first to identify gaps, then review explanations for any wrong answers. Retake after a few days for best retention.
Sample questions
-
1.Assertion (A): When a host fish species becomes extinct, its unique assemblage of parasites also meets the same fate. Reason (R): This is an example of co-extinction, in which species associated in an obligatory way become extinct together.
- A.Both A and R are true and R is the correct explanation of A
- B.Both A and R are true but R is NOT the correct explanation of A
- C.A is true but R is false
- D.A is false but R is true
-
2.Assertion (A): The genetic diversity shown by the medicinal plant Rauwolfia vomitoria over its distributional range is an example of diversity at the genetic level. Reason (R): A single species may show high diversity at the genetic level over its distributional range.
- A.Both A and R are true and R is the correct explanation of A
- B.Both A and R are true but R is NOT the correct explanation of A
- C.A is true but R is false
- D.A is false but R is true
-
3.Assertion (A): Some taxonomic groups like amphibians appear to be more vulnerable to extinction than others. Reason (R): Extinctions across taxa occur completely at random.
- A.Both A and R are true and R is the correct explanation of A
- B.Both A and R are true but R is NOT the correct explanation of A
- C.A is true but R is false
- D.A is false but R is true
-
4.The number of species in which group worldwide is more than the combined total of fishes, amphibians, reptiles and mammals?
- A.Insects
- B.Fungi
- C.Birds
- D.Molluscs
-
5.What is the significance of the slope (Z) of the regression line in a species-area relationship?
- A.For small areas its value is remarkably similar (0.1 to 0.2) regardless of taxon or region, but becomes much steeper (0.6 to 1.2) over very large areas like continents
- B.Its value is always exactly 1.0 for every taxonomic group
- C.It represents the Y-intercept of the species-area curve
- D.A higher slope always means lower species richness
