Vedclass · Answer

(B) In an ecosystem,trophic levels are defined based on the position of an organism in a food chain:$1$. The first trophic level $(T_1)$ consists of producers (autotrophs) like phytoplankton,grass,and trees $(P-III)$.$2$. The second trophic level $(T_2)$ consists of primary consumers (herbivores) like zooplankton,grasshoppers,and cows $(Q-II)$.$3$. The third trophic level $(T_3)$ consists of secondary consumers (carnivores) like birds,fishes,and wolves $(R-IV)$.$4$. The fourth trophic level $(T_4)$ consists of tertiary consumers (top carnivores) like humans and lions $(S-I)$.Therefore,the correct matching is $(P-III), (Q-II), (R-IV), (S-I)$.

Column-$I$	Column-$II$
$(P)$ First trophic level	$(I)$ Humans,Lion
$(Q)$ Second trophic level	$(II)$ Zooplankton,Grasshopper,Cow
$(R)$ Third trophic level	$(III)$ Phytoplankton,Grass,Trees
$(S)$ Fourth trophic level	$(IV)$ Birds,Fishes,Wolf

Match the following columns:
Column-$I$ Column-$II$
$(P)$ First trophic level $(I)$ Humans,Lion
$(Q)$ Second trophic level $(II)$ Zooplankton,Grasshopper,Cow
$(R)$ Third trophic level $(III)$ Phytoplankton,Grass,Trees
