Which statement explains the most realistic way to model energy flow in an ecosystem?

a. a food chain is most realistic because many organisms eat one type of food, and energy moves through a single pathway.
b. a food chain is most realistic because many organisms eat a variety of foods, and energy moves through different pathways.
c. a food web is most realistic because many organisms eat one type of food, and energy moves through a single pathway.
d. a food web is most realistic because many organisms eat a variety of foods, and energy moves through different pathways.

Correct answer is option D(.A food web is most realistic because many organisms eat a variety of foods, and energy moves through different pathways)

Explanation:

In ecosystem there are large number of living organisms, some of them are producer which produce food by photosynthesis some are herbivorous, some are herbivorous and carnivorous and some are only carnivorous. In ecosystem there are so many foods which a living organism can eat and this living organism also can be eaten by many animals. So energy flow through different pathways hence a food web is most realistic model to show energy flow in an ecosystem

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)
