4.4 Bioenergetics¶
This topic area explains how organisms capture energy, store it in useful molecules and release it when needed. Photosynthesis and respiration are the two key processes.
Core Role¶
- Connect energy capture in plants to energy release in cells.
- Make limiting factors and metabolic demand easier to reason about.
- Support later ecology by linking energy transfer to biomass and food production.
