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.

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.
Equipment
None required.
