Competition and adaptations in ecosystems
I can describe what plants and animals compete for, and consider how adaptations help organisms to survive and compete in their environment.

These resources will be removed by end of Summer Term 2025.
Switch to our new teaching resources now - designed by teachers and leading subject experts, and tested in classrooms.
These resources were created for remote use during the pandemic and are not designed for classroom teaching.
Lesson details
Key learning points
- Organisms compete for resources such as food, water, space, shelter, light, mates, pollinators and seed dispersers.
- The populations of species within a community are interdependent (they rely upon and affect one another).
- Organisms have adaptations that help them survive and compete in their environment.
- Adaptations can be physiological, structural or behavioural.
- Extremophiles are adapted to live in extreme environments, e.g. high salt concentration or very high or low temperature.
Keywords
Competition - Competition is when organisms in a community or population are seeking the same limited resource (e.g. food, mates).
Adaptation - An adaptation is a feature that organisms have to help them live in a particular place.
Physiological - Physiological adaptations are body processes that help an organism to survive and reproduce.
Microorganism - A microorganism is an organism that can only be seen using a microscope.
Extremophile - Extremophiles are organisms that are able to successfully survive and reproduce in extreme environments (e.g. very hot/very cold).
Common misconception
That organisms are able to quickly adapt to the place where they live.
Referring to inheritance, explain that changes to organisms take time to evolve - responses to any environmental change is not instant. In some organisms, where reproduction is slow, responses can be too slow to avoid extinction.

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.
