Answer & Solution

Answer: (Detailed Solution Below)

Option B: Pycnocline- Sea water salinity

Detailed Solution:

The correct answer is “Pycnocline- Sea water salinity”.

Ecocline refers to a gradual change in the ecological environment, but it is not specifically related to biodiversity. It refers to a transition zone where environmental conditions change, influencing species distribution.

Pycnocline is a layer in the ocean where there is a rapid change in water density, which is caused by a combination of temperature and salinity. It is not just related to salinity, but salinity plays a significant role.

Thermocline is the layer in the ocean where there is a rapid change in temperature with depth, not directly related to air temperature.

Halocline refers to a layer in the ocean where there is a rapid change in salinity with depth, not related to temperature.
