In this unit, students will learn that all species, including humans, are part of an interconnected global food web. A balance of these ecological interactions within a system is essential to the health and sustainability of the ecosystem. This unit explores the interdependence between biotic and abiotic components of an ecosystem. Students will:

  • describe how living organisms affect the survival of one another.
  • explain the biotic and abiotic parts of an ecosystem and their interactions.
  • predict how limiting factors such as physical, biological, chemical factors, etc. can affect organisms.
  • use evidence to explain how patterns in populations affect natural systems.
