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.

MRNA, is used to transcript DNA codes from DNA molecules and then later exits the nucleus via nuclear pore, then moves to the ribosome. Then, tRNA is activated to bring specific amino acid to the ribosome for translation. Ribosome, which is the site of synthesis of proteins, is composed of rRNA and ribosomal proteins.
A codon is a three-base sequence (three nitrogen bases in a row) on mRNA. An anticodon is a three-base sequence on tRNA. It matches the codon.
Epidermis is made up of dermis.
Answer:
Explanation:
Xylem transports and stores water and water-soluble nutrients in vascular plants.
Phloem is responsible for transporting sugars, proteins, and other organic molecules in plants.
Vascular plants are able to grow higher than other plants due to the rigidity of xylem cells, which support the plant.
Answer:
D
Explanation:
Vegetation on soil protects the soil from erosion because its roots and root hairs help bind the soil particles together. This occurs mechanically by binding soil into crumbs and also chemically by providing organic matter that binds the soil particle into humus that holds moisture. The soil becomes heavy to be carried off by wind erosion. Trees also break the down flow of water hence reducing the capacity of runoff to carry soil sediments.
