Create a mind map to summarise ecosystems and tropical rainforests. We’ve got a guide to creating mind maps if you need support.
The Final Countdown is here to help you prepare for your final AQA GCSE geography exam. Following our weekly exercises will prepare you to take on the examiner.
This week you will revise ecosystems and tropical rainforests. It would help if you covered the following:
- An example of a small-scale UK ecosystem to illustrate the concept of interrelationships within a natural system, an understanding of producers, consumers, decomposers, food chain, food web and nutrient cycling – Epping Forest
- The balance between components.
- The impact on the ecosystem of changing one component.
- An overview of the distribution and characteristics of large-scale natural global ecosystems.
- The physical characteristics of a tropical rainforest – vegetation | climate and the nutrient cycle
- The interdependence of climate, water, soils, plants, animals and people.
- How plants and animals adapt to physical conditions.
- Issues related to biodiversity.
- Changing rates of deforestation.
- A case study of a tropical rainforest to illustrate:
- causes of deforestation – subsistence and commercial farming, logging, road building, mineral extraction, energy development, settlement, population growth – (The Amazon | Malaysia)
- impacts of deforestation – economic development, soil erosion, contribution to climate change. (The Amazon | Malaysia)
- Value of tropical rainforests to people and the environment.
- Strategies used to manage the rainforest sustainably – selective logging and replanting, conservation and education, ecotourism and international agreements about using tropical hardwoods, and debt reduction.
Use one of the three strategies below to revise these areas.
Create flashcards to summarise ecosystems and tropical rainforests. We’ve got a guide to creating flashcards if you need support.
There are no quizzes for this week, but you can check out our interactive revision area for ecosystems.
Exam questions start next week. Contain your excitement.
