Can anyone plzzzz post the nitrogen cycle in a logical order?

How about take a look at this:
http://igbiologyy.blogspot.com/2014/03/112-nitrogen-cycle.html
(or try a youtube video that can help as well)
That website is good for revision but its according to 2014 syllabus.

Don't be! In Sha Allah it will be great btw frame your answers properly and take the time to read the question COMPLETELY and CAREFULLY! Don't just write things you know, give the examiner what he wants.
I know that ^ tip seems so obvious but sometimes in a rush we can forget.

Thanks, any tip at this point is helpful!!!
And thanks for the nitrogen cycle too, It helped alot!!!! (I nevr really understood it from the begginning!!!)

CAN U PLZ HELP ME IN MYJUNE 2013 ICT PAPER 12 QUESTION 18

Yeah sure! Its like u have to describe the EFT thingy,
What I have noticed is that sometimes writing the full form of the thing given enables u to gain a mark so just give the full form which is Electronic Funds Transfer at Point Of Sale Terminal
Then go on describing the whole EFT thing:
Customer inserts card into chip reader
Card is checked for validity/reported stolen
PIN is entered
PIN is compared with that stored on the chip
If PIN is OK/verified transaction is authorised
If not, customer is asked to re-enter PIN
Supermarket computer contacts customer’s bank
Checks if sufficient funds
If sufficient funds, transaction is completed/if not, transaction is rejected
Amount deducted from customer’s bank account
Amount credited to supermarket’s bank account
The supermarket EFTPOS terminal produces a receipt
This is like the ms answer but if u notice there are some repeating answers for some specific questions, this question is one of them......
Hope it helped!
