Vedclass · Answer

(C) food chain represents a linear sequence of organisms where nutrients and energy are transferred from one organism to another. $(i)$ Grass $\rightarrow$ Rabbit $\rightarrow$ Wolf $\rightarrow$ Lion. This is a valid food chain.$(ii)$ Plankton $\rightarrow$ Fish $\rightarrow$ Man. Grasshopper is a terrestrial herbivore and does not fit in this aquatic food chain. Thus,this group is not a valid food chain.$(iii)$ Grass $\rightarrow$ Snake $\rightarrow$ Wolf $\rightarrow$ Tiger. This is not a valid food chain because a snake (carnivore) cannot eat grass (producer),and a wolf does not typically eat snakes in this sequence. Thus,this group is not a valid food chain.$(iv)$ Grass $\rightarrow$ Grasshopper $\rightarrow$ Frog $\rightarrow$ Snake $\rightarrow$ Eagle. This is a valid food chain.Therefore,groups $(ii)$ and $(iii)$ are not constituents of a valid food chain.

Which group of organisms are not constituents of a food chain?
$(i)$ Grass,lion,rabbit,wolf
$(ii)$ Plankton,man,fish,grasshopper
$(iii)$ Wolf,grass,snake,tiger
$(iv)$ Frog,snake,eagle,grass,grasshopper
