Active transport occurs when a solute must pass through the cell membrane against its concentration gradient. A good analogy is that this is like pushing the water that fell over a waterfall, back up the river to the falls above.

Answer 2

We use a prison as an analogy for this. If the gate is open, the prisoners can easily or freely leave the prison cell. This will represent passive transport. In order to get prisoners in the cell, you have to put force on them and this will be active transport.
