Study Notes
Aquatic Environments
- The primary factor determining life in aquatic environments is light availability, which affects photosynthesis and ecosystem productivity.
- Freshwater environments have low salinity, while marine environments have high salinity, influencing species composition.
Swim Bladder
- The swim bladder in marine fishes helps regulate buoyancy, allowing them to maintain desired depths without expending energy.
Sunlight Zone
- The zone that receives sunlight and is located at the top of the water column is known as the photic zone, essential for photosynthetic organisms.
Coastal Environments
- Environments found at or near oceans and seas are termed marine environments, which include coastal areas and open waters.
Marine Mammals
- A common characteristic of marine mammals is their adaptation for life in water, such as streamlined bodies and the ability to hold their breath.
Sharks and Rays
- Sharks and rays possess unique features like cartilaginous skeletons, which provide flexibility and buoyancy.
Intertidal vs. Neritic Zone
- The intertidal zone experiences alternating exposure and submersion with tides, while the neritic zone is a shallow water area influenced by the continental shelf.
Concentrated Urine in Marine Organisms
- Marine organisms produce concentrated urine to conserve water in high-salinity environments, preventing dehydration.
Coastal Bird Adaptations
- A common adaptation of coastal birds is the ability to excrete excess salt through specialized glands, allowing them to thrive in saline environments.
Types of Marine Algae
- Types of marine algae include red, green, and brown algae; "lichens" do not belong to this category.
Marine Water Characteristics
- A primary characteristic that distinguishes marine water from freshwater is the higher salt content, influencing biodiversity and species interactions.
Salamander Habitat
- Sluggish, slow-moving streams ideal for salamanders are termed "lentic" environments, which support diverse aquatic life.
Diverse Fish Assemblages
- Coral reefs are known for having the most diverse assemblage of fishes, providing vital habitats and food sources.
Role of Phytoplankton
- Phytoplankton form the base of marine food webs, playing a vital role in oxygen production and carbon cycling in ecosystems.
