Why is collector current less than emitter current?

If the Emitter-Base junction is forward biased and the Collector-Base junction is reverse biased, the voltage across the device causes electrons from the emitter to flow to the collector. In this, electrons pass through the P-type lightly doped base region and some of the electrons recombine with holes. Therefore, the collector current is less than that of the emitter current.
