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

I believe the difference is that Tropical rainforests are warm and moist while the temperate rainforests are cool. Temperate rainforests have four seasons; spring, summer, fall and winter, while tropical forests experience warm weather all year round and do not have the same set of seasons. Additionally; tropical rainforests experience much higher rainfall than temperate rainforests.
