Solution

The correct option is D
A-1 B-2 C-4 D-3

Primary productivity is the amount of biomass or organic matter produced per unit area over a time period by plants during photosynthesis. It can be divided into gross primary productivity and net primary productivity

The rate of energy production by green plants using organic matter during photosynthesis is called as gross primary production (GPP).

The energy left after respiration and stored as organic matter in the producers is called as net primary production.

Amount of energy available at the consumer level for transfer to the next level is called as secondary productivity.

Q. Identify the incorrect pair.

I. Net Primary Productivity - Available organic matter for the consumers
II. Primary Productivity - Amount of production of organic matter during photosynthesis
III. Gross Primary Productivity - Amount of biomass produced per unit area over a certain period of time by plants during photosynthesis

Q. Assertion :Amount of organic matter synthesised by producers per unit time and per unit area during the process of photosynthesis is referred to as net primary productivity. Reason: Primary productivity is usually high and sustained throughout the year in temperate areas due to abundance of sunlight.

Q. Match column I with column II and select the correct option from the given codes.

Column I	Column II
A. Gross primary productivity	(i) Green plants
B. Secondary productivity	(ii) Rate of synthesis of organic matter by consumers
C. Transducers	(iii) Total organic matter produced from solar energy
D. Food web	(iv) Interconnection of food chains

Q. Match List I and List II.

List I	List II
a. Dry Cell	p. Primary cell
b. Lead Storage battery	q. 38% $H_{2} S O_{4}$
c. Ni-Cd cell	r. $M n O_{2} + C$
d. $H_{2} - O_{2}$ fuel cell	s. Secondary cell
