One of his observations was that the ice was not moving in the same direction as the wind. It was moving consistently to the right of the wind direction. This phenomenon would later become known as Ekman transport. As wind blows across the ocean, it moves water because of friction at the ocean surface.
Passive transport further helps in maintaining the dynamic equilibrium of gases, waste, water etc. No net equilibrium is maintained after the process of diffusion or osmosis. Key Differences. Active transport requires energy in the form of ATM while passive transport does not. In active transport molecules move against the concentration gradient but in passive transport, molecules move from high to low concentration.. Types of active transport are endocytosis, exocytosis.
