Study Notes
Freshwater Ecosystems
- Ponds and lakes support diverse plant life, including algae and reed species.
- Various animals inhabit these ecosystems, including fish, amphibians, and aquatic invertebrates.
- A notable example of a creature living underwater in freshwater is the trout, which thrives in these habitats.
Adaptations in Freshwater
- Trout exhibit adaptations like streamlined bodies and specialized gills for efficient swimming and oxygen extraction in flowing waters.
- Reed plants have deep roots that anchor them firmly to the bottoms of rivers and streams, showcasing adaptation to strong water currents.
Wetlands and Swamps
- Wetlands are characterized by water levels that remain close to the soil surface, creating unique habitats.
- Swamps play a crucial role in supporting biodiversity and serving as breeding grounds for birds and other wildlife.
Estuaries
- Estuaries have a unique feature of water that is saltier than that of rivers due to the mixing of freshwater and seawater.
- They are crucial natural habitats located where rivers meet oceans, enhancing ecological diversity.
Ocean Ecosystems
- Oceans serve as habitats for a wide variety of life forms, primarily relying on sunlight for photosynthesis, which is the main energy source for marine plants.
- Sunlight penetration decreases with increasing ocean depth, leading to cooler temperatures and less light availability.
- Organisms in deeper ocean zones primarily feed on organic material that sinks from the surface, not on sunlight or geothermal energy, contrary to the previous claim.
General Notes on Aquatic Ecosystems
- Rivers and streams are essential to the hydrological cycle as they empty into ponds and lakes, facilitating water flow and nutrient cycling.
- Most aquatic organisms, especially in ocean depths, depend on sunlight-derived energy sources for survival.
