Sources:
1. Rivers
2. Lakes
3. Wetlands
4. Groundwater
5. Rainwater
Characteristics:
1. Low salinity
2. Variable temperature
3. pH range: 6.5-8.5
4. Dissolved oxygen levels: 5-15 mg/L
Importance:
1. Drinking water
2. Agriculture
3. Aquatic habitats
4. Recreation
5. Ecosystem balance
Freshwater ecosystems:
1. Rivers and streams
2. Lakes and reservoirs
3. Wetlands and marshes
4. Freshwater swamps
Threats:
1. Pollution
2. Over-extraction
3. Climate change
4. Habitat destruction
5. Invasive species
Conservation efforts:
1. Water management
2. Watershed protection
3. Habitat restoration
4. Sustainable practices
5. Education and awareness
Remember, it is a vital resource, and its conservation is essential for human well-being and the health of our planet!
