Use mathematical representations to support claims for the cycling of matter and flow of energy among organisms in an ecosystem.
Clarification statement: Emphasis is on using a mathematical model such as a pyramid of biomass/energy to describe the transfer of energy from one trophic level to another and that matter and energy are conserved as matter cycles and energy flows through ecosystems. Emphasis is on atoms and molecules such as carbon, oxygen, hydrogen and nitrogen being conserved as they move through an ecosystem.
Assessment boundary: Assessment is limited to proportional reasoning to describe the cycling of matter and flow of energy.
