Which of the following represents an example of the fibonacci sequence in nature? corn apple grape acorn

P.s.  i'm sorry, i really tried, i don't think i ever heard of this before.  google says: " fibonacci sequence  is a  series of numbers in which each number (  fibonacci number   ) is the sum of the two preceding numbers. the  simplest is the series 1, 1, 2, 3, 5, 8, etc." what i got from that was  1=1 then 1+2=3, 2+3=5, and 3+5=8
so with that being said i think it is corn. because if you think about it  logically corn has multiple steps that led to it being different things.  i think it is asking you to see if any of the 4 items can be added to another thing to equal something similar but different. for example, corn,  corn, dry, kernel. but with an apple, i guess ingredients, heat, time, apple pie. again i'm sorry, that's the best i could do, good luck and god bless. : )
