Biome - Definition, Examples, Facts & Quiz, FAQ, Trivia
Discover Earth's major communities of plants and animals adapted to specific environments
What is a Biome?
A biome is a large community of plants and animals that live in a specific type of environment. Biomes are defined by factors like:
• Climate (temperature and rainfall)
• Soil type
• Plants that grow there
• Animals that have adapted to live there
Think of biomes as nature's neighborhoods - each with its own special plants and animals that have learned to live in those conditions. Just like you wouldn't find a polar bear in the desert, each biome has organisms specially adapted to survive there.
Did You Know?
Biomes cover huge areas - some span entire continents! The boreal forest biome stretches across North America, Europe, and Asia.
Types of Biomes
Earth has many different biomes, but scientists often group them into five major types:
Aquatic
Water-based biomes including freshwater (lakes, rivers) and marine (oceans, coral reefs)
Forest
Dominated by trees; includes tropical rainforests, temperate forests, and boreal forests
Grassland
Open areas dominated by grasses; includes savannas and temperate grasslands
Desert
Very dry areas with specialized plants and animals adapted to little water
Tundra
Cold, treeless plains of the Arctic with permafrost and low-growing plants
Each biome has its own special plants and animals that have adapted to survive in those conditions. For example:
• Cacti store water in their stems to survive deserts
• Polar bears have thick fur and fat to stay warm in the tundra
• Monkeys in rainforests have prehensile tails to swing through trees
• Prairie dogs live in underground tunnels in grasslands
Why Biomes Matter
Biomes are incredibly important for life on Earth. Here's why we need to understand and protect them:
Oxygen Production
Forests and phytoplankton in oceans produce most of Earth's oxygen
Water Cycle
Biomes help regulate Earth's water through evaporation and precipitation
Biodiversity
Each biome contains unique species that can't live anywhere else
When biomes are damaged or destroyed, it affects the whole planet:
• Deforestation reduces oxygen and increases carbon dioxide
• Desertification turns fertile land into desert
• Coral reef destruction harms ocean food chains
• Climate change can shift biome boundaries
By understanding biomes, we can better protect these vital ecosystems and the plants and animals that call them home.
Protecting Biomes
You can help protect biomes by reducing waste, recycling, and learning more about conservation efforts in different ecosystems.

Biome Trivia
Discover some fascinating facts about Earth's biomes:
Rainforest Layers
Tropical rainforests have four distinct layers: emergent, canopy, understory, and forest floor. Each layer has its own unique plants and animals adapted to that environment.
Cold Deserts
Not all deserts are hot! Antarctica is actually the world's largest desert because it gets so little precipitation. The Gobi Desert in Asia can reach -40°F (-40°C) in winter.
Grassland Roots
Grassland plants have incredibly deep root systems - some prairie grasses have roots that extend 15 feet (4.5 meters) underground! This helps them survive droughts and fires.
Permafrost
The tundra's permafrost (permanently frozen ground) can be over 1,500 feet (450 meters) deep! When it thaws, it releases methane, a powerful greenhouse gas.
