How is flu season defined? What are the criteria for this definition?
How does the flu affect businesses and governments? Could it affect residents’ access to certain resources?

The flu is caused by influenza viruses that infect the nose, throat, and lungs. These viruses spread when people with flu cough, sneeze or talk, sending droplets with the virus into the air and potentially into the mouths or noses of people who are nearby.

people can misdiagnose themselves because they don’t always know that sicknesses can have the symptoms as others and they assume it’s the flu because it’s a known sickness.  

The flu, also known as the influenza virus, is diagnosed year-round in the United States. Fall and winter seasons are when the greatest impact is usually seen and, therefore, is considered the "flu season." Influenza activity has a period of greatest activity between December and February, but the activity can last until May.

The flu is a very dangerous disease that is thankfully not anymore in circulation. When people working in government jobs are affected by this disease it delays the time they come to work and therefore the country's business goes down.

Also a large amount of money is spent by the government to cure this disease and the government has to focus on the eradication of these diseases and waste time.

When infected people use some resources and many citizens use the same resource then a large number of people could get affected due to this and therefore the country's economy is reduced with the resources.

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.
