What is necessary to convert this pictire into food web? Why

Explanation

a. For converting the above food chain into food web, more animals or links that may be present in the terrestial ecosystem need to be added, e.g., Bluebird , rabbit, rat,deer, tiger, etc.
b. It is necessary to include these animals because food web is an intricate network of food chains which are interconnected at various levels.
c. For instance, if we include rat, it would be a food source for snake as well as eagle. Similarly, if we include a bluebird, it would feed on grasshopper and the bluebird is eaten by a hawk.
d. Thus, the food chain gets inter-connected at various levels, forming a intricate web instead of linear chain.
