Biomes of the World
A biome is a huge region with its own climate. Where you live decides how you live — temperature and rainfall shape which plants and animals can survive there.
🌍Four Biomes to Know
❄️TUNDRA
ClimateCold & dry · frozen ground (permafrost)
🌱 low shrubs & moss · 🦊 arctic fox
🌴TROPICAL RAINFOREST
ClimateHot & wet · the most biodiversity on Earth
🌳 tall vine-covered trees · 🦜 parrots
🏜️DESERT
ClimateVery little rain · extreme hot/cold temps
🌵 cactus (stores water) · 🦎 lizards
🌾GRASSLAND
ClimateSeasonal rain · grasses rule, few trees
🌱 tall grasses · 🦓 grazing animals
🌡️ Climate decides the biome
⚖️Living vs. Non-Living Parts
🪨Abiotic = non-living
- ☀️ sunlight & temperature
- 💧 water & rainfall
- 🪨 rocks, soil & air
🐾Biotic = living
- 🌳 plants & trees
- 🦊 animals & insects
- 🍄 fungi like mushrooms
🔑Key Terms
🌍Biome A large region with a specific climate and types of life.
🪨Abiotic Factor A non-living part of an ecosystem (sun, water, temperature).
🐾Biotic Factor A living part of an ecosystem (animals, plants, fungi).
🚦Limiting Factor Something that limits population growth (food, water, space).
❄️Tundra Cold, dry biome with permanently frozen ground (permafrost).
🌴Tropical Rainforest Hot, wet biome with the most biodiversity on Earth.
⭐
Remember: abiotic factors like temperature and rainfall decide which biome forms — and the climate shapes which living things can survive there!
