6. In 2000, a council planted indigenous trees as part of a reforestation programme. (a) Why were indigenous trees used instead of non-indigenous trees? A) indigenous trees will bring in more pests B) indigenous trees are less likely to survive C) indigenous trees will support more native wildlife D) indigenous trees will cause more damage to the soil (b) The animal biodiversity in this reforested area was measured from 2004 to 2017. Biodiversity is measured on a scale from 0 to 1. 0 = low biodiversity 1 = maximum biodiversity Figure 12 shows the results.

Step 1

Why were indigenous trees used instead of non-indigenous trees?

Answer

Indigenous trees were chosen because they will support more native wildlife (C). This ensures a more balanced ecosystem, as native species are more adapted to the local environment compared to non-indigenous ones.

Step 2

Analyze the animal biodiversity data from 2004 to 2017.

Answer

The data indicates that animal biodiversity initially showed an upward trend, peaking around 2010, after which it displayed fluctuations. Notable points where the biodiversity significantly dropped can indicate anomalies due to external factors such as environmental changes or disturbances in the area.

Step 3

Explain the observation at Point A.

Answer

The biodiversity at Point A appears to be anomalous and much lower than the trend observed in previous years. This could indicate that there are underlying issues affecting the ecosystem, such as a lack of food or shelter, particularly if extreme weather or changes in habitat have occurred.
