Non-renewable resource
Explanation:
The cheetahs can be considered a non-renewable resource. Non-renewable implies that a resource cannot be replenished at it current rate of depletion.
How much has the cheetah's population declined:
percentage declination = 
x 100
Population in 1990 = 100,000
Population today = 12,000
Percentage declination = 
x 100 = 83.3%
We can see that the cheetah has suffered a whooping 83.3% decline in their population.
A renewable resource is one that can be replenished as it is being used such as water, air, e.t.c.

Cell transport is movement of materials across cell membranes. Cell transport includes passive and active transport. Passive transport does not require energy whereas active transport requires energy to proceed. Passive transport proceeds through diffusion, facilitated diffusion and osmosis. The purpose of the transport proteins is to protect the cell's internal environment and to keep its balance of salts, nutrients, and proteins within a range that keeps the cell and the organism alive.
