Inspiration is an active process because during inspiration the muscles of the diaphragm and thoracic cavity contract and requires energy for contraction. Therefore it is called an active process(process which require energy).

In case of expiration muscles of the thoracic cavity undergo relaxation which do not require any energy.Hence it is called passive process.

Hope it helps!!!!
