Active transport - Against the concentration gradient( low concentration→high concentration) and hence, ATP( energy) is required. Therefore, it is ATP Dependent or can be called Uphill transport.

Passive transport - with protein (facilitated diffusion) and without protein( simple diffusion). Along the concentration gradient( high concentration- low concentration) No ATP( energy) is required. Therefore, it is ATP Dependent or can be said Uphill transport. Therefore, it is Downhill transport.
