Question

_______________ occurs when abiotic parameters like altitude, temperature (thermocline), salinity (halocline), depth, etc., gradually vary.

  1. Edge effect
  2. Ecocline
  3. Ecotone
  4. Edge

hintHint:

Ecocline occurs when abiotic parameters like altitude, temperature, salinity, depth, etc., gradually vary

The correct answer is: Ecocline


    • A gradual change in the species composition of an ecosystem is called ecocline.
    • It is a result of a gradual decrease in the features of an ecosystem.
    • It occurs when the abiotic factors of the ecosystem gradually vary.
