Photosynthesis and cellular respiration provide most of the energy for key processes. HS-LS2-3 At each link upward in a food web, only a small fraction of the matter consumed at the lower level is transferred upward, to producegrowth and release energy in cellular respiration at the higher level. HS-LS2-4 Energy drives the cycling of matter in ecosystems. HS-LS2-3
ESSENTIALQUESTION(S) fortheUNIT
| How does matter cycle and energy flow through ecosystems? How are photosynthesis and cellular respiration interdependent in terms of matter and energy? How do factors such as temperature and pH affect the rates of photosynthesis and cellular respiration? | |||||
