Study Notes
Compensation Depth
- Compensation depth is the zone where photosynthesis equals cellular respiration, allowing for balanced energy production.
- It is estimated that a minimum of 1% of light penetration is necessary to achieve this balance.
Light Penetration
- Enhanced light penetration in water occurs in environments with higher concentrations of particles and organisms.
- The absorption of light is greater when there is an increased presence of algae in the water column.
Shoreline Effects
- Compensation depth tends to increase with distance from the shore due to varying water conditions and light availability.
Non-Photosynthetic Animals
- Many non-photosynthetic animals reside below the compensation depth to avoid predation, benefiting from reduced visibility.
- These animals exhibit vertical migration at night, moving upwards where they may find food or less risk.
Day and Night Processes
- During daytime, both photosynthesis and cellular respiration are active, supporting energy needs for aquatic ecosystems.
- At nighttime, only cellular respiration takes place, as photosynthesis ceases without sunlight.
