Then breath (vital), by singing, obtained for himself eatable food. For whatever food is eaten, is eaten by breath alone, and in it breath rests. The Devas said: 'Verily, thus far, whatever food there is, thou hast by singing acquired it for thyself. Now therefore give us a share in that food.' He said: 'You there, enter into me.' They said Yes, and entered all into him. Therefore whatever food is eaten by breath, by it the other senses are satisfied.

In plain words: By its singing, the breath also won food for itself, because all food is eaten through the breath. The other powers asked for a share, so the breath invited them to enter it. That is why, when the breath takes in food, all the senses are fed too.
