High School Life Science
Trophic Energy Transfer and Biomass
Weigh the algae, weigh the shrimp, and follow the energy.
Students estimate algae biomass and brine shrimp biomass in the same system. They compare the two and see how much is lost between levels.
How the lab meets it
What students do that satisfies the standard
NGSS HS-LS2-4
Standard: Use mathematical representations to support claims for the cycling of matter and flow of energy among organisms in an ecosystem.
What the kit does: Students measure biomass at two trophic levels and calculate the transfer between them.
AP Biology
Where it fits: Investigation 10, Energy Dynamics.
What the kit does: Students track energy from algae to brine shrimp with real biomass numbers.
APES
Where it fits: Unit 1, The Living World: Ecosystems.
What the kit does: Gives students their own data for trophic levels and the 10 percent rule.
