Biomes are vast regions with similar climate, plants, and animals. Each one creates a unique habitat, often spanning continents, from tropical rainforests to arctic tundras.
Tundra: Life on Ice

The tundra, characterized by permafrost, is surprisingly rich in biodiversity. During its short summer, the landscape transforms, allowing migratory birds and caribou to thrive.
Deserts: More Than Sand
Deserts: More Than Sand
Deserts, known for extreme aridity, occupy one-fifth of Earth's surface. Nighttime can bring about a sudden burst of life, with many animals being nocturnal to conserve water.
Rainforests: Earth's Lungs
Rainforests: Earth's Lungs
Tropical rainforests, despite covering less than 3% of Earth's area, house over 50% of all species. They are vital for oxygen production and carbon storage.

Grasslands, also known as prairies or savannas, are fertile grounds for agriculture. They support vast herds of herbivores and are crucial for human food production.
Aquatic Biomes: Water Worlds

Aquatic biomes, including oceans, lakes, and rivers, cover about 75% of Earth's surface. Marine algae contribute more than 50% of our oxygen.
Boreal Forests: Carbon Sinks
Boreal Forests: Carbon Sinks
Boreal forests, or taigas, form the largest terrestrial biome. Acting as massive carbon sinks, they play a key role in regulating the global climate.
