Hi Suchinder,
If you're not familiar with blogging, it is not surprising that you want to know the term "Organic Search". It is quite simple and if you're a internet surfer, you definitely did "Organic Search" before.
Organic Search Results: It is the term used for highlighting the "search results" in various search engines like Google, yahoo and etc. If you googled something like "Smartphones", you will get relevant Search results based on the keyword, these are called "Organic Search Results". Paid search results will not be included in this category.
So, coming to Techulator. If you asked a hot topic on "Ask Expert" section it may get 1000 or more Organic visits {People who came here by searching the relevant keyword}. You can know how much your question gets by clicking on "Check Traffic" link on the top of your question. If your question have passed 1000 organic visits, you will get cash credits.
Hope you got the answers. Happy Earnings!
Thanks & Regards,
Harish
