none there all bad
yes bats are useful they eat insects and only during night
no the will kill all your plants by eating them.
Each instrument used in analytical chemistry has a useful working range. This is the range of concentration (or mass) that can be adequately determined by the instrument, where the instrument provides a useful signal that can be related to the concentration of the analyte .All instruments have an upper and a lower working limit. Concentrations below the working limit do not provide enough signal to be useful, and concentrations above the working limit provide too much signal to be useful. When calibrating an instrument for use, the experimenter must be familiar with both the lower and upper working range of the chosen instrument.
all of them they help keep the useful ones alive in a food chain which is useful to us

The answer depend on the instrument. And since you have not bothered to state which instrument, I cannot provide a more useful answer.
