Worked Solution & Example Answer:Which one of the following phrases defines the term biodiversity? Shade one circle only - AQA - GCSE Geography - Question 2 - 2021 - Paper 1
Step 1
Step 2
Using Figure 5, describe the location of areas with low biodiversity levels.
Answer
Areas with low biodiversity levels indicated in Figure 5 are primarily found in regions with harsh environmental conditions, such as arid zones or regions subjected to significant anthropogenic activities. These areas often exhibit minimal species variety due to limited resources, habitat destruction, or unfavorable climate.
Step 3
Using Figure 5, suggest one reason for the high biodiversity levels in area X.
Answer
One reason for the high biodiversity levels in area X is its favorable climatic conditions and ample resources, which promote the growth of various plant and animal species. Additionally, the area might possess diverse habitats that cater to different ecological niches.
Step 4
Outline one way that plants are adapted to the climate in either hot deserts or cold environments.
Answer
In hot desert environments, plants have adapted by developing extremely long roots to reach deep water supplies. This adaptation allows them to survive in an arid climate where water is scarce.
Step 5
Assess the importance of inaccessibility and extreme temperatures as challenges to development in one of the following environments.
Answer
In the hot desert environment, inaccessibility presents a significant barrier to development due to limited transportation infrastructure, making it difficult to supply resources and goods. Extreme temperatures further complicate development efforts, as they impose challenges for sustaining agriculture and establishing permanent settlements. For example, the harsh daytime temperatures can hinder construction work, while night temperatures can cause development equipment to malfunction.

Step 8
'Tropical rainforests should be protected from economic development.' Do you agree?
Answer
I agree that tropical rainforests should be protected from economic development due to their critical role in maintaining biodiversity, regulating the climate, and supporting indigenous communities. Economic activities such as logging and mining lead to habitat destruction and loss of species, which not only impacts global ecosystems but also contributes to climate change. Sustainable alternatives, such as ecotourism or sustainable harvesting, should be pursued to balance economic needs with environmental conservation.
