Study Notes
Importance of Water
- Water is crucial for the survival of all life forms on Earth.
- Living cells are enclosed by membranes that protect the organism from its surroundings.
Solubility of Gases
- Solubility of gases in salty ocean water is approximately 20-30% lower than in fresh water.
- Increased temperatures result in decreased solubility of gases.
Impact on Food Chains
- Changes in CO2 levels in water can influence phytoplankton and algae, key primary producers in aquatic ecosystems.
- Alterations to these organisms can have cascading effects on species higher in the food chain.
Adaptations of Deep-Sea Fish
- Deep-sea fish possess strong, durable arteries and veins to cope with the high water pressure found at great depths.
Water Regulation in Fish
- Multicellular organisms, like fish, manage excess water intake through the kidneys, excreting it as dilute urine.
- Excess water enters the body through skin, mouth, and gills, requiring efficient excretion mechanisms.
