The given line graph illustrates the exportion of wheat over three different countries from 1985 to 1990.
In, 1985 Australia exported almost 15 millions of tonnes of wheat; while, this figure increased slightly and stood at 16 million in 1986. After that this ratio decreased gradually from 14 millons of tonnes in 1987 to 11 millons of tonnes in 1990.
Over the same period, around 19 millons of tonnes of wheat was exported by canada in 1985; whereas this value fell significantly in following year. However, there was a rapid growth in exportion of wheat in 1988 by 25 millons of tonnes. In addtion, in 1990, it stood at 19 millons of tonnes. About European community, it started from 17 millons of tonnes in 1985; while, the figure of wheat exportion was increased and accounted at 21 millons of tonnesin 1990.
Overall, it can be seen that Australia exported the least amount of wheat; whereas, European community exported the highest amount of wheat in given period of time between 1985 to 1990.
