They eat rodents and are eaten by owls and hawks
They are important because without them, the rodent population could become too numerous. Rodents like to chew on tree roots and other plants for nutrients, but this kills the plant. Too many rodents can cause a mass imbalance leading to the death of hundreds of other animals

Answer:
Antibiotics inhibit enzymes specific to bacteria and have no effect on virally encoded enzymes
Explanation:
The specificity of the antibiotics to inhibits some  bacterial enzymes is one of the major reasons why antibiotic do not affect viruses.In addition  antibiotics are designed to  have a significant  destructive  effects on  the mechanisms of biochemical reactions in bacteria and its  physiology, e,g on the cells walls,( inhibiting the formation of peptydoglycans) on certain organelles e,g ribisomes (inhibiting protein synthesis) and on the DNA(disrupting replication). The virus physiology is different from bacteria, therefore the design of antibiotics will nor affect these same mechanisms in viruses, thus no specificity for the antibiotic to act on in virus
