Study Notes
Water Regulation and Balance in Terrestrial and Aquatic Environments
- Evaporation is a major cause of water loss for organisms on land, influenced by temperature and air water content.
- In aquatic environments, water and salt move down concentration gradients through diffusion and osmosis.
- Terrestrial plants and animals regulate internal water by balancing acquisition against loss.
- Terrestrial animals gain water through drinking, food, and absorption from the air, while losing water through evaporation and secretions.
- Terrestrial plants gain water from the soil and air, and lose water through transpiration and secretions.
- Small terrestrial animals can absorb water from the air, while desert animals have specialized methods for water acquisition.
- Camels and Saguaro cacti have adaptations to acquire, store, and conserve water in the desert.
- In aquatic environments, organisms face challenges related to water and salt balance, with different strategies for freshwater fish and marine bony fish.
- Freshwater fish actively take in water through their gills and excrete excess water as dilute urine.
- Marine bony fish lose water through their gills and make up for it by drinking seawater, with specialized cells secreting sodium and chloride.
- Marine invertebrates and sharks have body fluids hypoosmotic to the surrounding seawater.
- The balance of water and salt in aquatic environments is influenced by drinking, secretion, and osmosis.
