उत्तर
The food web is the network of many food chains, like the one given in the following picture.
Food web: Food webs are formed by intricate feeding relationships. Food chains are not linear and straight in any ecosystem found in nature. However, these are quite intricate.
A predator consumes prey, but it also runs the risk of becoming prey for another predator. For instance, frogs can eat a wide range of insects, but snake feeds on frogs.
Frogs and insects can both be consumed by the same bird. In any ecosystem, complex food webs are formed by the interactions between the different biological components.
