344651 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

344652 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
BIOXII14: ECOSYSTEM

344653 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.
