Q. Which one of the following is correctly matched?
(a) Ecocline – Biodiversity
(b) Pycnocline – Sea water density
(c) Thermocline – Air temperature
(d) Halocline – Sea water temperature
Answer: (b)
Given below are two statements, one is labelled as Assertion (A) and the other as Reason (R):
1. Ecocline – Biodiversity
– This is incorrect.
An Ecocline refers to a gradual transition or gradient between two ecosystems or communities, often marked by changes in environmental conditions (e.g., moisture, temperature). It is not directly related to biodiversity.
Which of the following is the correct sequence of phases of biotic succession?
2. Pycnocline – Sea water density
– This is correct.
A Pycnocline is a layer in a body of water where there is a rapid change in water density with depth. This change in density is typically caused by variations in temperature (thermocline) or salinity (halocline).
3. Thermocline – Air temperature
– This is incorrect.
A thermocline refers to a layer in a body of water where there is a rapid change in temperature with depth, not air temperature.
4. Halocline – Sea water temperature
– This is incorrect.
A halocline refers to a layer in a body of water where there is a rapid change in salinity with depth, not temperature.
