Worked Solution & Example Answer:Figure 2 shows the money spent on conserving biodiversity in the UK by the government - AQA - GCSE Biology Combined Science - Question 2 - 2021 - Paper 2
Step 1
Describe the trends in the money spent on conserving biodiversity from 2005 to 2011.
Answer
From 2005 to 2008, the money spent on conserving biodiversity increased from approximately £470 million to a peak of £690 million in 2008. After 2008, there was a decline, dropping to around £630 million by 2011. Therefore, the overall trend shows an initial increase followed by a decrease.
Step 2
Calculate the percentage decrease in the money spent on conserving biodiversity from 2013 to 2017.
Answer
To find the percentage decrease, we use the formula:
ext{Percentage decrease} = rac{ ext{money spent in 2013} - ext{money spent in 2017}}{ ext{money spent in 2013}} imes 100From the graph, we get:
- Money spent in 2013: £690 million
- Money spent in 2017: £460 million
Plugging in the values:
ext{Percentage decrease} = rac{690 - 460}{690} imes 100 = rac{230}{690} imes 100 \\ ext{Percentage decrease} ext{ (to 2 significant figures)} = 33.3 ext{ %}Step 3
