Answer :
Final answer:
Dust mites require a relative humidity level of at least 60% to grow effectively. Like many organisms, they rely on a certain level of moisture, or water activity, for growth and reproduction. If relative humidity drops below this level, the growth and reproduction of dust mites decline.
Explanation:
Dust mites, like many other microorganisms, depend on available moisture to grow. This necessary moisture level is also known as water activity (aw). While different organisms have different requirements, in general, a high level of moisture is needed for the growth of most microorganisms. Specifically, dust mites require a relative humidity level of at least 60% to effectively grow and reproduce.
Relative humidity tells us how much water vapor is in the air compared with the maximum possible. For dust mites, if the relative humidity drops below 60%, their ability to grow and reproduce declines.
For example, fungi such as Aspergillus spp. can tolerate drier environments with a water activity (aw) range of 0.8-0.75. On the other hand, other organisms may require higher humidity levels. In each case, understanding the necessary water activity for an organism's growth can aid in controlling its population.
