Question

if sodium and chloride ions from Salt enter a fish with no energy spent, what type of transport is this an example of?

Answer 1

Active transport: Movement of materials across a membrane that requires an input of energy from a cell. Movement of material against the concentration gradient (from low concentration to high concentration)

Passive transport: Movement of materials across a membrane that does not require energy from the cell. Movement of material against the concentration gradient (from high concentration to low concentration)

Hope this helps!

Answer 2

This is an example of passive transport.

Passive transport is the movement of ions or substances across a cell membrane without the expenditure of energy from the cell. The degree of passive transport relies on the level of permeability of the cell membrane. Filtration, osmosis, facilitated diffusion and simple diffusion are the four major types of passive transport.
