Lesson details

Key learning points

  1. An ecosystem is a natural system in which plants, animals and their non-living environment interact.
  2. Living and non-living things interract within a small-scale ecosystem.
  3. Food webs help us understand the interrelationships in a small-scale ecosystem.
  4. Nutrient cycles show how nutrients transfer across different stores within an ecosystem.

Keywords

  • Ecosystem - a community of organisms (such as plants and animals) that interact with one another and their non-living (abiotic) environment

  • Producer - an organism that is able to absorb energy from the sun through photosynthesis

  • Consumer - an organism that gets its energy by feeding on other organisms (animals and/or plant matter)

  • Food chain - the connections between different organisms (plants and animals) that rely on one another for their source of food

  • Decomposer - an organism such as a bacterium or fungus that breaks down dead plant or animal tissue or waste

Common misconception

That ecosystems are made up of plants and animals only.

An ecosystem is a community of living things interacting with one another and with non-living components of their environment, such as soil and climate.
