Choose the correct statements from the following I. A man eating curd belongs to 3rd trophic level II. A sparrow feeding on a herbivorous insect is a secondary consumer III. Rabbit and deer belong to the same trophic level
1 I, II, III only
2 I, II only
3 II, III only
4 I only
Explanation:
I. A man eating curd belongs to 3rd trophic level as curd is obtained from milk of herbivore \(\mathrm{T} 2\) II. A sparrow feeding on a herbivorous insect is a secondary consumer III. Rabbit and deer belong to the same trophic level- herbivore, all the statements are correct

The first trophic level in grazing food chain is always a green plant because
1 They along have capability to fix atmospheric \(\mathrm{N}_{2}\)
2 Rich in chlorophyll
3 Of wide distribution
4 Their capacity to convert light energy to chemical energy
Explanation:
Members of first trophic level are autotrophs- green plants as they convert light energy to chemical energy

Number of trophic levels in food chains is restricted because
1 Trophic efficiency of animals is less than that of plants
2 About \(90 \%\) of the energy in a trophic level is lost as it passes to the next higher level
3 Predator animals are larger than prey animals
4 Number of organisms always decreases from lower to higher trophic levels
Explanation:
The number of trophic levels in the grazing food chain is restricted as the transfer of energy follows 10 per cent law - only 10 per cent of the energy is transferred to each trophic level from the lower trophic level.

G F C's are i. Also called predatory food chains ii. Begin with detritus iii. Begin with producers iv. The major conduit for energy flow in aquatic ecosystems v. The major conduit for energy flow in terrestrial ecosystem
1 i, ii, iii are correct
2 iii, iv, v are correct
3 i, iii, iv are correct
4 ii, iv, v are correct
Explanation:
In an aquatic ecosystem, GFC is the major conduit for energy flow. As against this, in a terrestrial ecosystem, a much larger fraction of energy flows through the detritus food chain than through the GFC.
