What is the trophic level of rat in a food chain?
1 \(\mathrm{T} 1\)
2 \(\mathrm{T} 2\)
3 \(\mathrm{T} 3\)
4 \(\mathrm{T} 4\)
Explanation:
Rat belongs to \({\rm{T 2}}\) because it depends on grains / plants

Select the incorrect statement about food chains.
1 Grazing food chains (GFC) and detritus food chains (DFC) are interconnected
2 GFC begins with a species which eats no other species and ends with a species that is eaten by no other species
3 GFC begins with producers whereas DFC begins with dead organic matter
4 GFC is the major conduit for energy flow in terrestrial ecosystems while DFC is the major conduit for energy flow in aquatic ecosystems
Explanation:
GFC is the major conduit for energy flow in terrestrial ecosystems while DFC is the major conduit for energy flow in aquatic ecosystems.

Food web refers to
1 Food chain
2 Capturing solar energy by autotrophs
3 Transfer of energy from one trophic level to next trophic level
4 Interdependence of organisms on each other for food
Explanation:
Food web is network of food chains which became interconnected at various trophic levels so as to form a number of feeding connections among different organisms in a biotic community.

Assertion : The number of trophic levels in the grazing food chain is restricted as the transfer of energy follows 10 per cent law. Reason : Only 10 per cent of the energy is transferred to each trophic level from the higher trophic level.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect.
Explanation:
Only 10 per cent of the energy is transferred to each trophic level from the lower trophic level.
