Ecosystems and habitats

I can describe what makes an ecosystem, can identify features of habitats and explain how organisms are adapted to live in their habitat.

Lesson details

Key learning points

  1. Ecosystems are made up of living organisms, which interact and depend on each other, and their physical environment.
  2. Habitats are where plants and animals live, and they contain living (biotic) and non-living (abiotic) parts.
  3. Organisms interact with the environment in which they live.
  4. All species have adaptations which make them suited to their environment.
  5. Changes to the environment may make it harder for organisms to survive in a particular habitat.

Common misconception

Pupils use everyday meaning rather than ecological meaning of the terms population and community.

There is repetition of use of these ecological terms within this unit building on prior learning.

Keywords

  • Biotic - Biotic factors are the living components of an ecosystem.

  • Abiotic - Abiotic factors are the non-living components of an ecosystem.

  • Adaptation - An adaptation is a feature that organisms have to help them live in a particular place.

  • Ecosystem - An ecosystem is made up of all the living organisms in a place, interacting with each other and their non-living surroundings.

  • Habitat - A habitat is the place where an organism lives. It must provide food, shelter and a place to reproduce.

Use your local environment to look at different habitats to discuss the biotic and abiotic factors of these environments to bring the ideas to life.
