More than a quarter of Australian fifth graders believe yogurt is grown on trees and three out of four of them think cotton is an animal product, according to a study from the Australian Council of Education Research.

Primary industry plays a vital role in Australian's economy and society, but the gap between rural and urban communities is growing, contributing to a lack of understanding of where food and other basic necessities of life come from, the study reported, according to Sky News Australia.

About 1,000 Australian children between the ages of 10 and 12 participated in the survey, conducted by the Australian Council for Education Research.

Three-fourths of them hold the belief that cotton comes from animals while 27 percent say yogurt is grown on trees.

The findings pose the question, Are You Smarter Than a Fifth Grader?

The answer is a resounding yes.
