is it possible to find out which Service is running on the basis of port no which is open/listening?

If you have lsof installed you can run it as root and grep for LISTEN. E.g.
root@lcrmdb1:/root >lsof | grep ":ssh (LISTEN)"
lsof: WARNING: compiled for AIX version 5.2.0.0; this is 5.3.0.0.
sshd 209002 root 3u IPv4 0xf100020000632398 0t0 TCP *:ssh (LISTEN)
If you don't have lsof already installed you can choose this option.
Run the command netstat as root and grep it.
root@test/# netstat -an | grep LISTEN
