Ecosystem — BIOLOGY STD 12 Science — Question

Grazing food chain starts from chlorophyll containing producers.
This chain extented up to herbivores, carnivor, and decomposers.
Green plants are directly dependent on solar energy.
In an aquatic ecosystem, GFC is the major conduit for energy flow.
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.
In nature, it is possible to have so many levels producer, herbivore, primary carnivore, secondary carnivore in the grazing food chain.
