Zorluk: KolayEcological Factors and Their Measurement

An ecologist studying an aquatic ecosystem needs to measure the turbidity and depth of light penetration in a pond. Which of the following instruments is most suitable for this measurement?

  1. Secchi discCevap
  2. B
    Anemometer
  3. C
    Hygrometer
  4. D
    Barometer

Cevap

Secchi disc
The Secchi disc is specifically designed for aquatic sampling to quantify turbidity and determine the euphotic zone boundary based on light penetration.

Adım Adım Çözüm

1
Identify the target ecological factor being measured
The factor is turbidity / depth of light penetration in an aquatic habitat.
Different physical abiotic factors require specific measuring instruments designed for aquatic or terrestrial environments.
2
Select the corresponding measuring instrument
A Secchi disc is used to measure water transparency and light penetration depth.
The depth at which the alternating black and white quadrants on the disc disappear from view indicates the extent of light penetration.
