Assertion : A network of food chains existing together in an ecosystem is known as a food web. Reason : An animal like kite cannot be a part of a food web.

The process of transfer of energy from producers through a series of organisms i.e. from primary consumers to secondary consumers to tertiary consumers by process of eating and being eaten constitute a food chain, eg. grassland ecosystem. Food chains can never occur independently in ecosystem but various food chains are inter-connected with each other forming an interlocked system known as food web. In grassland ecosystem food chains may be- (i) Grass $\rightarrow$ Rabbit $\rightarrow$ Hawk/kite (ii) Grass $\rightarrow$ Mouse $\rightarrow$ Snake $\rightarrow$ Kite/Hawk (iii) Grass $\rightarrow$ Grasshopper $\rightarrow$ Lizard $\rightarrow$ Kite/Hawk So, the food web will include kite.
