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.
