Question
- A. Using plants to absorb metal compounds from soil
- B. Using bacteria to produce leachate solutions
- C. Burning plants to produce ash containing metals
- D. Displacing metals using scrap iron
Answer
The correct option is Using plants to absorb metal compounds from soil. This answer is correct because it matches the approved learning objective to evaluate biological methods of metal extraction from information provided. (HT only) in the subtopic Alternative methods of extracting metals.
Explanation
The correct option is Using plants to absorb metal compounds from soil. Using plants to absorb metal compounds from soil is correct because it directly supports the approved learning objective to evaluate biological methods of metal extraction from information provided. (HT only). This belongs to the subtopic Alternative methods of extracting metals within Using the Earth's resources and obtaining potable water, so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from Alternative methods of extracting metals.
Common mistake
Misunderstanding Biological Methods
Students often confuse the processes of phytomining and bioleaching, thinking they are the same.
Do not treat this as a general statement about HT only. Instead, answer by clearly linking the correction to evaluate biological methods of metal extraction from information provided. (HT only) in Alternative methods of extracting metals. This keeps the response inside Using the Earth's resources and obtaining potable water and prevents a vague or off-topic GCSE answer. The mistake to avoid is: students often confuse the processes of phytomining and bioleaching, thinking they are the same.
