(1.9C) Interdependence Among Organisms


Gather evidence of interdependence among living organisms such as energy transfer through food chains and animals using plants for shelter.

  • Food Chains

    Food Chains

    Living things need a source of energy or food in order to survive. The flow of energy begins with organisms that can create their own food using an external source of energy (generally the Sun). Other living things must obtain their energy by consuming other organisms. In the signature lesson, students model a simple food chain to understand interdependence of organisms through energy transfer.
