Lesson details
Key learning points
- Growing food helps feed the increasing human population, but can have negative impacts on ecosystems and biodiversity.
- The use of peat and destruction of peat bogs as an example of a negative impact.
- Eutrophication as an example of a negative impact.
- The introduction of non-indigenous species as an example of a negative impact.
- Ways of mitigating some of these negative impacts.
Keywords
Biodiversity - Biodiversity is the range of different living organisms that live in a place.
Fertiliser - Fertiliser are minerals that are added to the soil to help plants to grow.
Eutrophication - Eutrophication is the process in which a body of water is overly enriched with plant nutrients. This leads to excessive growth of simple plants such as algae.
Indigenous species - Indigenous species are the species that occurs naturally in an ecosystem. They are sometimes referred to as native species.
Common misconception
A common misconception is that the excessive growth of the plants in eutrophication is the cause of a reduction in biodiversity as a result of the plants using up the oxygen in the water.
Steps in eutrophication are outlined. Increased minerals cause the growth of plants at the surface resulting in the death and decomposition of the plants. Decomposition results in microbes using oxygen, resulting in biodiversity loss.

The starter quiz will activate and check your pupils' prior knowledge, with versions available both with and without answers in PDF format.
We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
