The food chain that is shown in the food web could be any of the following:
- tree → deer → mountain lion
- grass → rabbit → mountain lion
- grass → rabbit → hawk
- grass → grasshopper → frog → snake → fox
- grass → grasshopper → snake → hawk
- grass → grasshopper → snake → fox → mountain lion
- tree → caterpillar → robin → fox → mountain lion
<h3 /><h3>FURTHER EXPLANATION</h3>
A food chain shows a unidirectional feeding relationship among organisms in an ecosystem. The organisms occupy a certain "place" in the food chain called trophic level. Food chains may have several trophic levels which always begin with the producers.
- Producers are organisms which make their own food. Plants are examples of producers.
- The organisms the directly feed on the plants are called the primary consumers. They are either herbivores or omnivores.
- The organisms that feed on the primary consumers directly are called secondary consumers. Those that feed on the secondary consumers are called tertiary consumers and quaternary consumers feed on tertiary consumers. These are either omnivores or carnivores.
- The apex predator is the animal at the top of the food chain. It is preys on the organisms in the lower trophic levels but nothing preys on it.
A food web, on the other hand, is a series of food chains showing the interdependence of organisms in an ecosystem.

The correct answer is option C, that is, viruses.
An infection occurs when a foreign species moves inside the body of an individual and causes harm. The species utilizes the body of that person to reproduce, sustain itself, and colonize. These infectious species are called pathogens. The examples of pathogens are viruses, bacteria, prions, and fungi.
Of the given options, viruses are the smallest infectious agent. The viruses are basic particles, which must infect a host cell to reproduce and develop. Viruses utilize the host cells metabolic machinery to double themselves.
The right answer is B) gene.
A gene, in genetics, is a basic unit of heredity which in principle predetermines a specific trait of the form of a living organism, as defined in 1909 by Wilhelm Johannsen. From the physical point of view, a gene is a fragment of the determined locus of a DNA sequence.
A gene "parameter" the synthesis of a given RNA, by predefining its structure and, therefore, that of the possible protein or possible polypeptide synthesized from this RNA: this is what molecular biology studies .
These two aspects of the notion of gene are supposed to correspond, one at the physical and molecular level, the other at the level of principle and heredity.
