Using the Earth's resources and sustainable development: state examples of natural products that are supplemented or replaced by agricultural and synthetic products
You need to give examples of natural products that humans use, and explain how agricultural or synthetic products can supplement or replace them.
- 3 key terms
Study notes
From the checked teaching notes for this specification point.
The idea
You need to give examples of natural products that humans use, and explain how agricultural or synthetic products can supplement or replace them. For instance, natural rubber from rubber trees can be supplemented or replaced by synthetic rubber made from crude oil. Natural fertilisers such as manure can be supplemented or replaced by synthetic fertilisers produced from ammonia. Natural fibres such as cotton and wool can be supplemented or replaced by synthetic fibres such as polyester and nylon. When answering, name the natural product, name the agricultural or synthetic alternative, and state whether it supplements or replaces the natural product.
What earns the marks
- Identify natural products such as rubber, cotton, wool, silk, timber and natural fertilisers.
- Identify agricultural products such as crops, manure and compost that can supplement natural products.
- Identify synthetic products such as synthetic rubber, polyester, nylon and synthetic fertilisers that can replace natural products.
- Explain that agricultural products come from farming while synthetic products are made by chemical processes, often from crude oil.
- State whether a named product supplements or replaces a natural product, using the correct term.
Common mistakes and how to put them right
Confusing supplement with replace.
Put it right: A supplement is used alongside the natural product, while a replacement is used instead of it.
Giving a synthetic product without naming the natural product it replaces.
Put it right: Name both for full credit.
Assuming all synthetic products are made from crude oil.
Put it right: Some are made from other raw materials, so check the example.
Exam tips
- Use a table to compare natural, agricultural and synthetic products if the question asks for several examples.
- Name specific products rather than vague categories, such as 'polyester' instead of 'synthetic fibre'.
- Check whether the question asks for one example or several, and give the required number to avoid losing marks.

You need to give examples of natural products that humans use, and explain how agricultural or synthetic products can supplement or replace them. For instance, natural rubber from rubber trees can be supplemented or replaced by synthetic rubber made from crude oil. Natural fertilisers such as manure can be supplemented or replaced by synthetic fertilisers produced from ammonia. Natural fibres such as cotton and wool can be supplemented or replaced by synthetic fibres such as polyester and nylon. When answering, name the natural product, name the agricultural or synthetic alternative, and state whether it supplements or replaces the natural product. A strong answer earns marks for these points. Identify natural products such as rubber, cotton, wool, silk, timber and natural fertilisers. Identify agricultural products such as crops, manure and compost that can supplement natural products. Identify synthetic products such as synthetic rubber, polyester, nylon and synthetic fertilisers that can replace natural products. Explain that agricultural products come from farming while synthetic products are made by chemical processes, often from crude oil. Exam tip: Use a table to compare natural, agricultural and synthetic products if the question asks for several examples.
