Match List I with List II regarding trophic levels and their corresponding examples in a food chain. List I (Trophic Level) List II (Examples) A. First trophic level i. Wolf, Fishes B. Second trophic level ii. Man, Lion C. Third trophic level iii. Phytoplankton, Grass D. Fourth trophic level iv. Zooplankton, Cow Choose the correct answer from the options given below:
Options
- AA(iii), B(iv), C(i), D(ii)
- BA(iii), B(iv), C(ii), D(i)
- CA(iv), B(iii), C(i), D(ii)
- DA(iii), B(i), C(iv), D(ii)
Correct answer
A. A(iii), B(iv), C(i), D(ii)
Step-by-step solution
According to the trophic levels in an ecosystem: Producers like phytoplankton and grass form the first trophic level (A matches with iii). Primary consumers (herbivores) like zooplankton and cow feed on producers and form the second trophic level (B matches with iv). Secondary consumers (carnivores) like fishes and wolf feed on herbivores and form the third trophic level (C matches with i). Tertiary consumers (top carnivores) like man and lion form the fourth trophic level (D matches with ii). Therefore, the correc
