Question

Number of trophic level in GFC are restricted due to :-

Answer 1

as there are only primary consumers

Answer 2

HLO MATE HERE IS UR ANSWER.

⭐. Grazing Food Chain ( GFC ) is also called as predatory food chain.

⭐. It starts with producers ( green plants ) and ends with secondary carnivores.

⭐. Generally in a grazing chain , at the 1st trophic level greeb plants perform photosynthesis.

⭐. At the first trophic level only one percentage of the solar energy is converted into chemical energy.

⭐. GPP , NPP herbivores at second trophic level are not efficient in using the NPP and converting them into GSP and a lot of energy is wasted.

⭐. so if there are many trophic levels in a grazing food , the subsequent energy transfers will be more , which may not completely fulfill the energy needs of the mich more higher trophic levels.

⭐. So the number of trophic levels in GFCś is restricted.
