Column I	Column II
A. Bacteria	(i) Prisere
B. Green plants	(ii) Transducers
C. Primary succession	(iii) Lithosere
D. Succession on bare rock	(iv) Micro-consumers

• A. A-(iv), B-(ii), C-(i), D-(iii)
• B. A-(iv), B-(iii), C-(i), D-(ii)
• C. A-(i), B-(iii), C-(ii), D-(iv)
• D. A-(iv), B-(ii), C-(iii), D-(i)

Answer 1

Answer: (A)

A-(iv), B-(ii), C-(i), D-(iii)

Bacteria are important decomposers of ecosystem. Because of their small size, they are also called as micro consumers. Green plants(producers) are also called transducers because they convert light energy into chemical energy.

Primary succession(=Prisere) is the biotic succession that occurs on a previously bare area. Lithosere(or Xerosere) refers to the sequence of successional stages that occur on bare rock.

So, the correct answer is 'A-(iv), B-(ii), C-(i), D-(iii)'
