a. Examples of goods and services provided by tropical rainforest ecosystems (food stuffs, medicines, timber and recreation).
This statement asks you to know what tropical rainforests provide for people and to give examples of each type. Goods are physical products that can be harvested or sold, such as food stuffs (fruit, nuts and game), medicines (compounds from rainforest plants used to treat illness) and timber (hardwoods such as mahogany). Services are benefits that come from the ecosystem working, and recreation is the key example, such as ecotourism and wildlife watching in protected areas. A strong answer gives one clear example for each category and says briefly why it matters. For instance, quinine, used against malaria, was derived from cinchona bark.
b. How climate change presents a threat to the structure, functioning and biodiversity of tropical rainforests.
This statement asks how climate change could threaten rainforest structure, functioning and biodiversity. Structure means the layered canopy, understorey and emergent trees; heat and drought can kill large trees, opening gaps and simplifying layers. Functioning means processes such as transpiration, nutrient cycling and carbon storage; less transpiration can reduce local rainfall, creating a feedback loop. Biodiversity means the variety of species; species with narrow tolerances may be unable to move fast enough, so extinction risk rises. Use a real example, such as the Amazon droughts of 2005 and 2010, to show cause and effect.
c. Economic and social causes of deforestation (conversion to agriculture, resource extraction, population pressure).
Deforestation in tropical rainforest has economic and social causes. Conversion to agriculture involves clearing forest for cattle pasture, plantations of crops such as soya or palm oil, or small subsistence plots. Resource extraction includes commercial logging for timber and mining or oil extraction, often opening access roads that enable further clearing. Population pressure arises when growing or migrating communities need land, food and income, so settlement spreads into forest edges. Learners should name each cause, state the economic or social driver behind it, and link it to a specific loss of forest.
d. Political and economic factors (governance, commodity value and ecotourism) that have contributed to the sustainable management of a rainforest in a named region.
Sustainable management of a rainforest in a named region depends on political and economic factors working together. Governance refers to laws, enforcement, protected area designation and land rights that control who may clear forest and how. Commodity value means the market price of products such as timber, rubber, Brazil nuts or carbon credits, which can make standing forest more profitable than cutting it. Ecotourism generates income from visitors, giving local people a reason to protect wildlife and trails. Learners must select one named region and show how each factor has contributed to sustainable management there, rather than describing rainforest in general.

Tropical rainforest ecosystems provide a range of goods and services, some of which are under threat exam tips
Marking Points
- Names at least one good and one service provided by rainforests, such as timber or recreation.
- Identifies food stuffs, medicines and timber as goods that can be harvested or sold.
- Identifies recreation, such as ecotourism, as a service that depends on the ecosystem remaining intact.
- Gives an accurate, rainforest-specific example for each category rather than a generic example.
- Explains briefly why each example matters to people, such as its economic or health value.
- Explains a specific way climate change affects rainforest structure, such as drought killing large emergent trees.
- Explains how changes to transpiration or nutrient cycling affect rainforest functioning.
- Explains how species with narrow tolerances face extinction risk or range shifts, reducing biodiversity.
- Links each impact to a cause, such as rising temperature or altered rainfall, rather than listing effects alone.
- Uses an accurate named example, such as the Amazon droughts of 2005 and 2010, to support the explanation.
- Identifies conversion to agriculture as forest clearance for cattle pasture, plantations or subsistence plots.
- Identifies resource extraction as logging, mining or oil extraction that removes forest and may open access roads.
- Identifies population pressure as growing or migrating communities needing land, food and income.
- Explains the economic or social driver behind each cause rather than naming the cause alone.
- Links each cause to a specific loss of forest cover or a change in land use.
- Distinguishes human causes from natural causes of forest loss when choosing between options.
- Identifies governance as laws, enforcement, protected area designation or land rights that control forest clearance.
- Explains commodity value as the market price of forest products that can make standing forest more profitable than cleared land.
- Explains ecotourism as income from visitors that gives local people a reason to protect the forest.
- Names a single rainforest region and keeps every factor linked to that region.
- Shows how each factor has contributed to sustainable management rather than only describing it.
- Distinguishes political factors, which concern rules and control, from economic factors, which concern income and value.
Examiner Tips
- 💡Read each option and check that it covers both goods and services before selecting it.
- 💡Eliminate options that name non-rainforest sources, such as plantations or temperate forests.
- 💡When two options look similar, choose the one that names a service dependent on the intact ecosystem.
- 💡Organise your answer under the three headings of structure, functioning and biodiversity.
- 💡Write one cause and effect chain for each heading, starting with a change in temperature or rainfall.
- 💡Use a named example with an accurate date and check that it illustrates the point you are making.
- 💡Read every option and eliminate any that describe natural causes or non-economic, non-social processes.
- 💡When two options seem correct, check which one names a specific economic or social driver rather than a general effect.
- 💡Match each stem to one of the three named causes and confirm the driver in the stem supports that cause before selecting.
- 💡Read each option and check whether it names a political factor, an economic factor, or a specific named region before selecting it.
- 💡Eliminate options that describe rainforest threats rather than factors that have contributed to sustainable management.
- 💡When options differ on the factor, match it to the definition: rules and control for governance, income and value for commodity value or ecotourism.
Common Mistakes
- Treats recreation as a good because it involves a product; correct this by classing recreation as a service that the ecosystem supports.
- Lists temperate woodland or plantation products as rainforest examples; keep every example tied to tropical rainforests.
- Gives only timber and omits food stuffs, medicines and recreation; cover each type named in the statement.
- Focuses on sea-level rise as the main threat; focus instead on temperature and rainfall change, which act directly on the forest.
- Lists effects of climate change without stating how each one damages structure, functioning or biodiversity; explain the link for each.
- Confuses biodiversity with the number of trees; biodiversity is the variety of species, so describe species loss or range change.
- Treats deforestation as the only threat; present climate change as a separate threat that can act alongside land clearance.
- Lists population growth as the only cause; include conversion to agriculture and resource extraction as well.
- Describes deforestation as a natural process such as fire or storms; select the economic or social cause that is human-driven.
- Names a cause without explaining how it removes trees; state the driver and the land-use change it produces.
- Describes governance as only a government's wish to help; state the specific laws, enforcement or protected area designation involved.
- Treats commodity value as the price of any product without linking it to standing forest being worth more than cleared land.
- Discusses rainforest in general without naming a region; select one named region and apply each factor to it.
