2.2 Measuring the abiotic components of the system
2.2.1 - List the significant abiotic (physical) factors of an ecosystem.
Some abiotic factors of an ecosystem are: water, PH, Temperature, Light intensity, Salinity, Turbidity, Dissolved oxygen.
|
2.2.2 - Describe and evaluate methods for measuring at least three abiotic (physical) factors within an ecosystem.
Here are some indicators and tools used to measure them:
pH - pH meter Temperature - Thermometer (C degrees) Dissolved oxygen - Oxygen meter (PPM) Light intensity - Light meter (LUX) Salinity - Salinity meter (ppt) Turbidity - Secchi circle (Visibility) Marine - salinity, dissolved oxygen, wave action Freshwater - turbidity, temperature, dissolved oxygen Terrestrial - temperature,wind speed, particle size, slope, soil moisture, drainage, mineral content. |
