Question
_______________ occurs when abiotic parameters like altitude, temperature (thermocline), salinity (halocline), depth, etc., gradually vary.
- Edge effect
- Ecocline
- Ecotone
- Edge
Hint:
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.
