Living indicators are species that are sensitive to changes in the environment. For example air pollution can be monitored by looking at lichen, which are sensitive to sulphur dioxide in the air. The number of lichen at a particular location indicates how clear the air is. Similarly, mayfly larvae are good indicators for water pollution because they're sensitive to the concentration of dissolved oxygen in water.
Non-living indicators are things like satellites which can measure the temperature of the sea surface, weather stations that measure atmospheric temperature, rain gauges to measure rainfall, and dissolved oxygen meters to measure concentration of dissolved oxygen in water.
A blood hemoglobin measurement of 13.5 g/100 ml would be a normal level of measurement.
Hemoglobin is a protein in red blood cells that transports oxygen. How much hemoglobin is in your blood is determined by the haemoglobin test? The most significant part of red blood cells is hemoglobin. It is made up of heme, a protein that binds oxygen. Adults typically achieve a range of outcomes, but in general: Male: 138–172 grams per liter (g/L) or 13.8–17.2 grams per deciliter (g/dL). Women: 121–151 g/L or 12.1–15.1 g/dL. The nominal level of measurement is the first measurement level. The variables' numbers are only used to categorize the data at this level of measurement. Words, characters, and alphanumeric symbols can all be employed at this level of measurement.
