Aquatic life uses may be hampered when the entire water body experiences daily fluctuations in dissolved oxygen levels as a result of plant respiration at night. Extreme oxygen depletion can lead to death of desirable fish species. 5.

Photosynthesis: How do plants get energy?

labsci.stanford.edu

Created by LABScI at Stanford 2 Key Concepts: • Photosynthesis is the primary means by which plants get their energy. They derive this energy from a sugar called glucose (C 6 H 12 O 6). • To make glucose, sunlight is captured in pigments like chlorophyll, the substance that gives leaves their green color.
