Question

Biogeochemical cycle can be traced in
(a) Ecosystem
(b) Only water
(c) Biomes
(d) Only atmosphere

Choose the correct option:

• A. a and b
• B. a and c
• C. b and c
• D. c and d

Answer 1

The correct option is B a and c

Biogeochemical cycle can be traced in an ecosystem and biomes as both are same except that an ecosystem can be as small as a pond while biomes are only the large ecosystem whose boundaries are determined by altitude and longitude. Thus in Option 2, both ‘a’ and ‘c’ statements are correct.
