Question

Match List-I with List-II
\[\begin{array}{|l|l|} \hline \textbf{List-I} & \textbf{List-II} \\ \hline \text{(A). Population size} & \text{(I). It refers to how many individuals reside in a particular area} \\ \hline \text{(B). Population density} & \text{(II). It yields helpful information about how species interact with each other} \\ \hline \text{(C). Population distribution} & \text{(III). It represents the total number of individuals in a habitat} \\ \hline \text{(D). Population dispersion} & \text{(IV). It describes how individuals of a species are spread out, whether they live in close proximity} \\ \hline \text{to each other or far apart, or clustered into groups} \\ \hline \end{array}\]
Choose the correct answer from the options given below:

• (A) - (I), (B) - (III), (C) - (II), (D) - (IV)
• (A) - (II), (B) - (IV), (C) - (I), (D) - (III)
• (A) - (IV), (B) - (II), (C) - (III), (D) - (I)
• (A) - (III), (B) - (I), (C) - (IV), (D) - (II)

Hint:

Focus on the most unambiguous matches first. Population size is the total count (III), and population density is the count per area (I). This will often help you narrow down the options to the correct answer, even if other parts of the question are slightly confusing.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
The question requires matching fundamental terms in population ecology with their correct definitions.

Step 2: Detailed Explanation:
Let's define each term and find its best match:
\[\begin{array}{rl} \bullet & \text{(A) Population size: This is the total number of individuals in the population. This directly matches with (III) It represents the total number of individuals in a habitat. } \\ \bullet & \text{(B) Population density: This is the number of individuals per unit area or volume. This directly matches with (I) It refers to how many individuals reside in a particular area. } \\ \bullet & \text{(D) Population dispersion: This refers to the pattern of spacing among individuals within the boundaries of the population (e.g., clumped, uniform, or random). The description (IV) It describes how individuals of a species are spread out... is the definition of dispersion. However, in the given options, C is matched with IV. } \\ \bullet & \text{(C) Population distribution: This refers to the geographic area within which a species can be found. In the context of the options, it has been matched with (IV) It describes how individuals of a species are spread out.... While this is technically the definition of dispersion, it's the intended match in this question's logic. } \\ \bullet & \text{By the logic of the chosen correct answer, (D) Population dispersion is matched with (II) It yields helpful information about how species interact.... This is a consequence or an inference from dispersion patterns (e.g., uniform dispersion suggests competition), rather than a definition.} \\ \end{array}\] Despite some imprecision in the definitions for C and D, the combination that correctly pairs the clearest terms (A with III, and B with I) is found only in option (4). A-(III), B-(I), C-(IV), D-(II).

Step 3: Final Answer:
Based on the process of elimination and the most accurate pairings, the correct option is (4).
