Which one of the following phrases defines the term biodiversity? Shade one circle only - AQA - GCSE Geography - Question 2 - 2021 - Paper 1

Areas with low biodiversity levels are typically located in regions with extreme environmental conditions, such as deserts or polar regions. These areas often have limited resources, leading to fewer species being able to thrive and reproduce.

One reason for the high biodiversity levels in area X could be the presence of a variety of habitats and microclimates that support a wide range of species. This ecological diversity allows for niche differentiation and higher survival rates for various organisms.

In hot deserts, plants such as cacti adapt by developing thick, fleshy stems that store water. Additionally, they have a waxy coating on their surfaces to minimize water loss through evaporation, enabling them to survive long periods of drought.

I choose the hot desert environment. Inaccessibility in hot desert regions often means limited infrastructure and difficulty in reaching resources. Extreme temperatures further complicate development efforts, making it challenging to sustain agriculture or establish permanent settlements. The harsh conditions necessitate specialized adaptations for both flora and fauna, limiting economic opportunities.

The mean global forest loss from 2011 to 2017 is calculated as 23.4 million hectares.

The correct answer is B: 68%. This reflects the significant loss in forest area over the mentioned period, highlighting environmental concerns.

I agree that tropical rainforests should be protected from economic development. The rich biodiversity within these ecosystems is irreplaceable and provides essential services such as carbon storage, habitat for countless species, and regulation of global climate. While development may offer short-term economic gains, the long-term consequences on biodiversity and environmental stability can be detrimental.
