Paper 1 · People, Development and Environment

Given below are two statements, an Assertion (A) and a Reason (R). Choose the correct answer.

Assertion (A):Microenvironment refers to the immediate local surroundings of the organism, and macro-environment refers to all the physical and biotic conditions that surround the organism externally.

Reason (R):Environment refers to both the abiotic (physical or non-living) and biotic (living) environment.

ABoth (A) and (R) are true and (R) is the correct explanation of (A) ✓ Correct

BBoth (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

Correct answer: (A) Both (A) and (R) are true and (R) is the correct explanation of (A)

Explanation

Both the assertion and the reason are true, and the reason correctly explains the assertion.

The assertion rightly separates the microenvironment as an organism's immediate surroundings from the macroenvironment as all external physical and biotic conditions.

The reason states that environment covers both the abiotic non-living and the biotic living components.

Because environment is made of these abiotic and biotic conditions, the micro and macro scales simply describe them at different ranges.

The reason thus supplies the basis on which the assertion's two-level definition rests.

Soil moisture around a single root is a microenvironment, while a whole forest climate is a macroenvironment.
