1. Intro to NPP

3. Gross Primary Productivity

5. Secondary Net Productivity
Amount of biomass produced by primary consumer (cellular respiration)
Amount of energy available to secondary consumer

8. Amount used in plants by
Cellular Respiration
Amount available to primary
Consumers
Amount used as waste to
decomposers
Light energy absorbed by
producers

10. Amount used in Cellular Respiration
Amount available to secondary consumers (Net
Secondary productivity)
Amount as waste
Primary NPP from
Plants that is
Consumed by
Butterfly larvae
