Worked practice questions

In the introductory NCERT account, biodiversity refers to which pair?

  1. Number and types of organisms
  2. Body mass and age of organisms
  3. Cell size and cell shape
  4. Growth rate and lifespan
Show answer and solution

Correct answer: A. Number and types of organisms

Biodiversity refers to the number and types of organisms present on Earth. It concerns the variety of living organisms, not measurements of one individual.

Why does grouping organisms into categories help biologists?

  1. It gives every species the same name
  2. It removes variation within species
  3. It makes vast diversity easier to study
  4. It makes all organisms interbreed
Show answer and solution

Correct answer: C. It makes vast diversity easier to study

Millions of organisms cannot be studied individually with equal ease. Categories based on shared characters make this diversity manageable. Classification does not remove variation or make organisms interbreed.

Which sequence runs from a broader to a narrower taxonomic rank?

  1. Family → order → class
  2. Species → genus → family
  3. Class → phylum → kingdom
  4. Order → family → genus
Show answer and solution

Correct answer: D. Order → family → genus

The full descending hierarchy is kingdom → phylum/division → class → order → family → genus → species. Thus order → family → genus proceeds from broader to narrower ranks.
