Study Notes
Vegetation and Climate
- Vegetation growth depends on climate, resulting in diverse biomes worldwide.
- Sunlight and water are essential for all plants to thrive, leading to adaptations for varying conditions of light and rainfall.
- Warmer, wetter climates promote more vegetation, whereas colder, drier climates limit it.
Temperate Forests
- Characterized by deciduous trees that shed leaves annually.
- Experience changing seasonal conditions unlike rainforests, which maintain warm and moist climates year-round.
Forest Biomes
- Cover approximately one-third of Earth's surface but are rapidly declining due to deforestation.
- Serve as habitats for the majority of terrestrial species and are categorized into distinct types.
Boreal Forests
- The largest land biome, primarily composed of dense evergreen forests.
- This biome has the coldest and driest climate of all forest types.
Tropical Rainforests
- Defined by dense vegetation, high temperatures, and significant rainfall.
- Among the oldest land biomes, they host the highest diversity of plant and animal species.
Agricultural Factors
- Crop growth is influenced by multiple factors including soil quality and agricultural practices, with temperature and rainfall being critical.
- Unsuitable climate conditions can prevent the growth of certain crops in specific regions.
Importance of Vegetation
- Vegetation offers shelter for various wildlife and serves as a human resource.
- Provides materials like timber for construction and plants for herbal medicine.
Crops
- Certain vegetation types, when cultivated in large quantities, are classified as crops, which are essential for human consumption.
Wheat
- Wheat is the most significant global food crop, serving as the main staple for about 30% of the global population, nearly 2.5 billion people.
- It is processed into flour used for products such as bread and pasta.
Impact of Climate Change
- Rapid global warming alters climate conditions, with some regions becoming hotter and drier while others experience increased rainfall.
- Climate change threatens wheat production, with many previously productive farms now endangered, which may lead to food shortages and famines if trends continue.
