Which homeostatic process moves particles against a concentration gradient?

Active transport is a correct answer

Explanation:

Active transport is the homeostatic process in which particles move against the concentration gradient.

The molecules move across the membrane from the low concentration to high concentration.

In this process, energy is required which is provided in the form of ATP for the movement of the molecule.

There are three types of Active transport

Example of Active transport:

a bird that nests only in a particular tree species.

carbon traps heat so more of it makes it hotter causing global warming. during the ice age carbon levels in the atmosphere were low so it got very cold. so the common things between them is carbon levels in the atmosphere.
