HES Activity 4.3 Assessment


Check to see if students are making the connection that photosynthesis causes the inorganic pool to shrink and the organic pool to grow, whereas cellular respiration causes the opposite trend. Students might also suggest that photosynthesis causes a “flux” to the biomass pool, and cellular respiration causes a “flux” to the atmosphere pool. In addition, check that students are understanding how combustion contributes to the atmosphere pool and is not balanced by a different flux.
