The end result of succession with a stable, unchanging final state is called climax community.

Explanation:

The end result of succession with a stable, unchanging final state is called climax community.

The climax community consists of species that have adapted to the conditions of the area and exist in equillibrium with each other and environment. It is the stable state of succession.

examples are tundra and tropical rainforests.

The climax community is changed if destruction by fire or evolutionary changes over the period of time. The evolutionary change could be in even one of the species.

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.
