Big Idea

Living things are diverse, can be grouped, and interact in their ecosystems.



  • Biodiversity: the variety of different types of living things in an ecosystem.
  • Characteristics of local plants, animals and fungi.


  • Population: all the members of the same type of living thing (species) in an area.
  • Communities: different populations in an area living together.
  • The interconnection between living and non-living things in the local environment.
  • Our shared responsibility to care for the local environment.
