Passive absorption of minerals depends onPassive absorption of minerals takes place by diffusion, ion exchange and mass flow, along a concentration gradient, without using metabolic energy (ATP).
So it is not affected by metabolic inhibitors (which affect only active absorption).
However, the rate of diffusion depends on temperature, since molecules move faster at higher temperature.
So passive absorption of minerals depends on temperature.
