Question

Match List I with List II:

LIST I - Ecological Parameters	LIST II - Unit of Measurement
A. Net primary productivity	I. g/m2
B. Absorbed photosynthetically active radiation	II. g/L
C. Phosphorus	III. Joules/area/year
D. Plant biomass	IV. gC/area/year

Choose the correct answer from the options given below:

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

Hint:

Units of ecological parameters vary widely; ensure you associate each parameter with its specific measurement scale.

Answer 1

The Correct Option is A

• Net primary productivity (A): Measured in \( gC/\text{area}/\text{year} \), as it represents the carbon fixed by plants in a given area over time.
• Absorbed photosynthetically active radiation (B): Measured in \( \text{Joules}/\text{area}/\text{year} \), reflecting the energy absorbed by plants for photosynthesis.
• Phosphorus (C): Measured in \( g/L \), representing its concentration in a solution.
• Plant biomass (D): Measured in \( g/m^2 \), representing the total mass of living plant matter per unit area.
