Band 4+: The first graph below shows the weight (in tonnes) of fruit produced by a farm during each month in 2013, and also the amount (in tonnes) of fertiliser used. The second graph shows the volume of rainfall in each month (in millimetres). Write a report summarising the information. Select and describe the main features, and make comparisons where relevant.

The charts illustrated the fruit produced in a field per month in 2013, the fertilizer used and the monthly rainfall in that year.

There was a significant increase in the number of rainfall at 12 mm in January, subsequently achieving a peak at 16 mm in February before experiencing a gradual decline to 4 mm in July. Additionally, the trend maintained the same level to September. Then, there was a significant increase in fertilizer between January and April from 0,5 ton to 0,9 ton. After that in May the fertilizer experienced a moderate fall where the fertilizer only reached 0,1 ton. June and September showed a period of volatility in fertilizer from 0,1 ton to 0,4 ton. Initially, the weight of fruit increased to the peak at 4,2 tons in September.

Subsequently, the amount of rainfall had significantly risen between September and December, from 11 mm to 14 mm. Then in September and December this showed an oscillation in fertilizer from 0,1 ton to 0,4 ton. Lastly, the amount of fruit reduced dramatically to the lowest position all time between September and December, from 4,2 tons to 0,2 tons.

Overall, the bigger the volume of rainfall, the smaller fertilizer was needed to empower the plants. Meanwhile, the weight of the fruit produced grew gradually as the volume of rainfall reduced.
