A transistor actively modifies current (bipolar type transistors) or voltage (FET types), based on control currents or voltages.
Passive components only passively store energy, or modify voltage with respect to current as a linear function.

A transistor is an active element because it absorbs power and uses that power to affect the flow of current in a circuit.
For more information, do an internet search on "basic transistor circuits."

Basically, a transistor is an active element, because for a small change in the input, you get a larger change on the output. It might be voltage or it might be current, depending upon the circuit. It can even be impedance!
Whatever the type, bipolar, FET, etc. the story is the same. More out for less in.

Yes. Because it can control current flowing through its collector with a much smaller current through flowing its base.
