Study Notes
Water Regulation in Terrestrial and Aquatic Environments
- Evaporation is a significant cause of water loss for organisms on land, influenced by temperature and air water content
- Diffusion and osmosis determine water movement in aquatic environments
- Terrestrial organisms face challenges of water loss through evaporation and reduced access to replacement water
- Terrestrial animals regulate internal water through a balance of acquisition and loss
- Terrestrial plants regulate internal water through a balance of gain and loss, including water absorption and transpiration
- Small terrestrial animals can absorb water from the air, while desert animals have specialized water acquisition methods
- Camels and Saguaro Cacti have unique approaches to acquiring, storing, and conserving water in desert environments
- Aquatic organisms have different challenges in water and salt balance, with freshwater fish facing hyperosmotic conditions and marine bony fish facing hypoosmotic conditions
- Freshwater fish absorb water through their gills and excrete excess water as dilute urine, while marine bony fish drink seawater and have specialized cells for salt balance
