Which of the following is an example of an ecosystem service?

• Human population growth

• Water purification

• Per-capita consumption

• Technological advancement

Answer explanation

Water purification is an ecosystem service as it refers to the natural processes that filter and clean water, benefiting both the environment and human health. The other options do not represent ecosystem services.

What does the term 'impurity' refer to in the context of water purification?

• A method of recycling nutrients

• A substance that contaminates water

• A design solution constraint

• A type of biodiversity

Answer explanation

In water purification, 'impurity' refers to any substance that contaminates water, making it unsafe or unsuitable for use. This definition aligns with the correct answer, distinguishing it from the other options.

Which process is involved in nutrient recycling?

• Soil erosion

• Decomposition of organic matter

• Increase in human population

• Water purification

Answer explanation

Decomposition of organic matter is crucial for nutrient recycling as it breaks down dead plants and animals, returning essential nutrients to the soil, which supports new plant growth. The other options do not directly contribute to this process.
