Description en-US:
Use a mathematical representation to support claims for the cycling of matter and flow of energy among organisms in an ecosystem.
Comment en-US:
Clarification Statement: Emphasis is on using a mathematical model of stored energy in biomass 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.
Comment en-US:
Assessment Boundary: Assessment is limited to proportional reasoning to describe the cycling of matter and flow of energy.
