Difficulty: MediumEcological Factors and Their Measurement

In an ecological investigation comparing microclimatic conditions across a savanna ecosystem, a researcher needs to quantify the speed of air currents. Which of the following instruments is designed for this specific measurement?

  1. AnemometerAnswer
  2. B
    Wind vane
  3. C
    Hygrometer
  4. D
    Barometer

Answer

An anemometer is the instrument used to measure wind speed.
An anemometer is the standard ecological instrument calibrated to measure wind speed, an essential climatic factor affecting transpiration and evaporation rates.

Step-by-Step Solution

1
Identify the target abiotic ecological factor described in the stem.
The target factor is the speed of air currents (wind speed).
The scenario highlights measuring how fast air moves across a savanna ecosystem.
2
Match the target factor with its standard ecological measuring instrument.
An anemometer is chosen.
Anemometers consist of rotating cups or propellers calibrated to record wind speed.
