Lesson details
Key learning points
- All consumers, including humans, depend on producers because they make all of the food for the rest of the food chain.
- Plants produce edible seeds and fruits after pollination (transfer pollen from the anthers of flowers to the stigma).
- Many plants depend on animals such as insects to pollinate them, and on animals such as birds to disperse their seeds.
- Because of food chains and pollination, producers and consumers are interdependent.
- Pollinators are important, ensuring there is food security for humans (having enough food to feed the human population).
Keywords
Producer - A producer is an organism that makes its own food.
Pollen - Grains of pollen carry genetic material between flowers to enable flowering plants to reproduce.
Pollination - Pollination is the process where pollen is transferred to the female organs of a plant, to enable seeds to be made.
Interdependent - Organisms are interdependent when they rely upon each other for their survival.
Food security - Food security is having enough food to feed the human population.
Common misconception
The interdependence of organisms within ecosystems arise from more than just feeding relationships.
This lesson demonstrates that feeding relationships are important and that producers often rely on consumers for reproduction.

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.
