Arthropods are fed on (or preyed on) by the animals and birds according to the food web. Therefore, a decrease in arthropod population will cause a subsequent decrease in that of animals too. This is because the animal population will compete for the fewer arthropods. This increased competition will lead to a survival of the fittest and a subsequent decrease in the animal population.
Explanation:
A food web is used to indicate the cycle of food, through feeding relationships, in an ecosystem hence concomitantly also show the flow of energy in the ecosystem. Food webs are made of several to many interlinked food chains.
Usually the primary producers are at the bottom of the food chain while tertiary consumers are at the top.

The picture is a scientific model which is used to explain the concept of the water cycle by means of pictures and descriptions.
<h3>What is a scientific model?</h3>
A scientific model is a representation which may be in form of pictures, illustrations, objects, or ideas which are used to explain a particular concept by scientists.
Scientific models are usually employed to explain either difficult to understand concepts or scarcely observable phenomena in order to enrich the knowledge and comprehension of others.
The given illustration is an example of a scientific model. It is used to explain the concept of the water cycle. By means of pictures and descriptions, the various processes of the water cycle can be fully comprehended.
Also, by means of a cyclical illustration, the model helps to explain that the water cycle is a continuous repetitive process.
In conclusion, scientific models may be in form of pictures, illustrations or objects.

Answer:
A) proteins in the cell will include lysine instead of phenylalanine at amino acid positions specified by the codon UUU.
Explanation:
Anticodon is the name given to each set of nucleotides complementary to the triads of nucleotides found in mRNA. As you may already know, each nucleotide is formed by a nitrogenous base; in the case of RNA, the nitrogenous bases are adenine (A), uracilla (U), guanine (G) and cytosine (C), each nitrogenous base binds with its complementary nitrogen base. For this reason, a codon formed by the UUU crack will have as its anticodon a crack formed by AAA.
Based on this, we can conclude that in a mutant bacteria that binds lysine to tRNAs with the AAA anticodon instead of normal phenylalanine, proteins in the cell will include lysine instead of phenylalanine at the amino acid positions specified by the UUU codon.
