Study Notes
Ecosystem Classification
-
Artificial Ecosystems: Human-altered or maintained environments such as urban areas, artificial lakes, and reservoirs.
-
Natural Ecosystems: Divided into aquatic and terrestrial types; these systems can self-maintain and self-renew.
Biomes
-
Biomes: Communities of plants and animals sharing characteristics suited to their environment; found across various continents.
-
Distinct Biological Communities: Biomes develop in response to shared physical climates.
Aquatic Ecosystems
-
Aquatic Ecosystem Definition: Ecosystems located in bodies of water, including oceans, rivers, and lakes.
-
Factors Influencing Aquatic Biomes:
- Sunlight penetration capability
- Nature of the bottom substrate
- Water temperature
- Amount of dissolved materials in water
Marine Ecosystems
-
Open Marine Ecosystem: Includes marine life like algae, plankton, jellyfish, and whales; organisms thrive in the euphotic zone (up to 150 meters deep).
-
Ocean Floor Ecosystem: Diverse marine life including fish, crustaceans, and seaweed exists in the ocean floor, relying on organic matter for survival in deeper waters.
-
Coral Reef Ecosystem: Highly productive, found in warm tropical waters; hosts about one-quarter of marine species, including fish, snails, and sponges.
Specialized Aquatic Ecosystems
-
Estuary Ecosystem: Shallow areas at river mouths where fresh and saltwater mix; important as nurseries for fish and shrimp, with lower species diversity compared to open oceans.
-
Mangrove Ecosystem: Coastal saltwater swamps with saline-tolerant trees; they support diverse life forms, including fish, birds, and crustaceans.
Freshwater Ecosystems
-
Freshwater Ecosystem Definition: Characterized by low salt levels and varying temperatures; includes lakes, rivers, streams, and ponds.
-
Lakes and Ponds: Two categories of standing freshwater systems; oligotrophic lakes are nutrient-poor, cold, and deep.
