Lesson details
Key learning points
- Microorganisms and detritivores (detritus feeders) are responsible for the decomposition of plant and animal material.
- Decay is needed to keep nutrients cycling around an ecosystem.
- Compost is made out of decomposed plant and animal material.
- Biogas is produced when waste material is anaerobically digested.
- Biogas contains methane which can be harvested and used as a fuel.
Keywords
Microorganism - A microorganism is an organism that can only be seen using a microscope.
Decomposer - A decomposer is an organism that feeds on the remains of other living organisms (organic matter).
Decay - Decay is the breakdown (or rotting) of organism matter by bacteria, fungi, or other organisms.
Detritus - Detritus is the remains of living organisms.
Enzyme - An enzyme is a protein that acts as a biological catalyst (a substance that speeds up a reaction).
Common misconception
Decomposers release energy that is recycled back to plants.
Decomposers break down dead organisms and waste. This returns minerals to the soil which can be used by plants. It is worth stating that some decomposers are eaten by carnivores as part of food chain diagrams which include decomposers.

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.
