The food web starts with plants and finishes with the top meat eater, the vulture.

In the primary evolved way of life, the plants are eaten by the grasshopper, and the grasshopper, thus, is eaten by the vulture.

Plants → Grasshopper → Vulture

In the subsequent evolved way of life, the plants are eaten by the hare. The bunny is then devoured by the vulture.

Plants → Rabbit → Vulture

In the third natural way of life, the plants are eaten by the rodent. The rodent is then eaten by the vulture.

Plants → Rat → Vulture

In the fourth natural pecking order, the plants are eaten by the rodent, the rodent is eaten by the snake, and the snake, thusly, is eaten by the vulture.

Plants → Rat → Snake → Vulture

In the fifth natural way of life, the plants are eaten by the grasshopper, and the grasshopper, thusly, is eaten by the frog. The frog is eaten by the snake, and the snake is devoured by the vulture.

Plants → Grasshopper → Frog → Snake → Vulture

At long last, in the 6th natural way of life, the plants are eaten by little birds which thusly are eaten by the vulture.

Plants → Small birds → Vulture

Answer

Food Web

Each living thing in an ecosystem is part of multiple food chains. A food chain is a sequence of who eats whom in a biological community (or an ecosystem) to obtain nutrition. Each food chain is one possible path that energy and nutrients may take as they move through the ecosystem. All of the overlapping and interconnected food chains in an ecosystem make up a food web.

A food web is a graphical representation of feeding relationships among species in an ecological community, that is, of who eats whom. Typically, species are connected by lines or arrows called “links”, and the species are sometimes referred to as “nodes” in food web diagrams.

Organisms in food webs are organized into categories called trophic levels. There levels are divided into:

1. Producers (first trophic level) – Who make their own food and do not depend on any other organism for nutrition (eg. Plants)
2. Primary Consumers: Herbivores who eat plants, algae and other producers (eg. Mouse)
3. Secondary consumers that eat herbivores (Eg. Snake who eats mouse)
4. Tertiary consumers that eat secondary consumers (Eg. Eagle who eats a snake)
5. Decomposers (last trophic level) who eat non-living plant and animals remains (Eg. Fungi, Bacteria)

Food web is differs from a food chain in that the latter shows only a portion of the food web involving a simple, linear series of species (Eg. Predator, herbivore, plant) connected by feeding links. A food web depicts a more comprehensive picture of the feeding relationships and can be considered as a bundle of many interconnected food chains occurring within the community.
