Active transport requires energy when moving molecules against a concentration agent. It requires for specific membrane transport proteins. Only a certain type of protein can move a certain type of substance.
The three main types of Active Transport are:
1) Sodium-Potassium Pump
2) Endocytosis
<span>3) Exocytosis </span>

Exponential growth happens when the resource is enough and competition is low. The example for this condition is when a small population move to a resourceful area. If the area having many resources, that means the area is favorable.
A low density population will need less resource. It is hard to get exponential growth in a high density population as the competition for the resource will be high.</span>
