Study Notes
Freshwater Habitat Temperature Variation
- Seasonal changes in air temperature are the primary drivers of temperature variation in freshwater habitats in the temperate zone.
Marine Flora Growth
- Light availability and nutrient concentration are crucial factors influencing the growth of marine flora.
Freshwater Habitat Stratification
- Freshwater habitats can be broadly classified into two main divisions based on stratification:
- Lentic - Still water habitats like ponds and lakes
- Lotic - Flowing water habitats like rivers and streams
Soil Layers
- The O horizon (also known as the organic layer) is rich in decomposed organic matter and nutrients. This layer is crucial for supporting plant life.
Soil Types and Characteristics
- Sandy soils are characterized by large particle size, good drainage, and poor water retention.
- Clayey soils have small particle size, poor drainage, and high water retention.
- Loamy soils are a mixture of sand, silt, and clay, offering a balance of drainage and water retention.
