Neelam,
Since the word hosted does not appear, it means that you can go ahead and associate your blogs with the AdSense account without any need for an upgrade. I assume that you have created blogs at the Google-owned platform blogger.com. If so, just open your blog, go to 'Earnings' in the left side pane, and read the text there. You will see the feature to connect the blog to AdSense. It is important to note, though, that AdSense approval for the blog will not happen unless you have good-quality content and are regularly doing so. I have a couple of blogs where I no longer put up posts regularly, so these no longer have an AdSense association.
Also, as I indicated, I do not want to give you any false hopes of earning through blogs. None of my blogs are earning avenues as such, with just $2 in the last three years from one, and just one cent in the last three years from another!! I continue to put in content, though, as I love writing and it is a wonderful way to do something interesting, to take time off from regular work. So if you love writing poems, do continue just as a passion for it. Once on a trip, somebody asked me why I spend time and effort on blogs when I am not earning from them and my answer silenced him "Not everything needs to be done with the goal to make money. It is just joy doing something that I love."
Also, if you wish, I will contact you by email directly and will be happy to share through direct communication with you what I learned through Tony Sir, Ankit, and online sources about blogging.
