What is Ecosystems Under Human Pressure?
This topic explores the structure and functioning of ecosystems, including concepts such as trophic levels, energy flows, and nutrient cycling. It investigates the value of ecosystems and the threats they face from human activities, such as deforestation, pollution, and the introduction of invasive species. The topic also examines different approaches to ecosystem management and conservation.
Board notes: Covered by AQA, Edexcel, and OCR. AQA has a focus on the concept of ecosystem resilience. Edexcel requires students to have a detailed case study of a threatened ecosystem. OCR often includes questions on the role of different players in ecosystem management.
Step-by-step explanationWorked examples
Worked example 1: Core method
When asked to 'assess the value of a tropical rainforest ecosystem', a student should consider its economic, ecological, and social value. The answer could include the value of timber and non-timber forest products, the role of the rainforest in regulating the climate and protecting biodiversity, and its importance for indigenous communities. The answer should conclude with a justified judgement on the overall value of the ecosystem.
Worked example 2: Exam variation
Now change one detail in the question and keep the same structure: name the Ecosystems Under Human Pressure idea being tested, show the method or evidence, then explain why it answers the command word. This helps A-Level Geography students avoid memorising one surface pattern.
Worked example 3: Mark-scheme check
Finish by checking the answer against marks: one point for the correct Ecosystems Under Human Pressure idea, one for accurate working or evidence, and one for a precise final statement. If any step is vague, rewrite it before moving to timed practice.

Frequently asked questions
What is biodiversity?
Biodiversity is the variety of life on Earth, from the smallest bacteria to the largest animals. It includes genetic diversity, species diversity, and ecosystem diversity.
How can we manage ecosystems sustainably?
Sustainable ecosystem management involves using the resources of an ecosystem in a way that meets the needs of the present without compromising the ability of future generations to meet their own needs. This can be achieved through a combination of conservation, restoration, and sustainable use.
