Topic: Need for Classification
Multiple Choice Questions
Q1. The primary reason for classifying living organisms is to:

- Count the total number of species on Earth
Q2. Which of the following is NOT a benefit of classification?

- It makes all organisms look the same
- It helps in understanding biodiversity
Q3. The science of naming, defining and classifying organisms is called:

- There are millions of species with diverse characteristics
- All organisms look exactly the same
- Scientists have nothing better to do
Q5. Which of the following would be most difficult WITHOUT a classification system?
- Counting the number of students in a class

APPLICATION / ANALYSIS
Q12. A new species of frog is discovered in the Western Ghats of India. Scientists want to study it, name it, and understand its place in the living world.
(a) How would classification help scientists communicate about this new frog to other scientists around the world?
(b) Why is it important to know which other frog species this new species is related to?(c) A student argues: "Classifying this frog is a waste of time. We should just study it directly." Do you agree? Give reasons.
Q13. In your school library, books are arranged by subject: Science, Maths, History, Literature, etc. Within Science, there are sections for Physics, Chemistry, Biology, and so on.
(a) How is this arrangement similar to the classification of living organisms?
(b) What problems would you face if all books were mixed randomly on the shelves? Relate this to the problems of not classifying living organisms.
(c) Can you think of ONE disadvantage of classifying books strictly by subject? Does this disadvantage also apply to biological classification?
