The benefit of Type 5 indicators is the ability to provide a distinct pass/fail result providing the confidence of sterility prior to releasing the load.

Bioindicators are species that can be used as a measure of some aspects of an ecosystem's health. The species' population or health may be a proxy for the ecosystem's health. For example, lichens are often used as indicators of air quality. Since they don't have roots and get a lot of their nutrients from the air, they are a trustworthy indicator of an area's air quality. Another example is some algal species being used as measures of water pollution.
