Welcome to the Biosphere—the sphere of life!

The Biosphere includes all living things on Earth: animals, plants, fungi, and even tiny microbes. Life is everywhere—in oceans, forests, deserts, and even extreme places like hot springs and icy poles.

In the Biosphere, everything is connected. Plants grow in soil from the Geosphere, absorb water from the Hydrosphere, and use sunlight and air from the Atmosphere to make food through photosynthesis.

Animals eat plants or other animals, breathe the air, and drink water. Even tiny organisms help break down dead plants and animals, returning nutrients to the soil.

By studying the Biosphere, we learn how all life is linked and why it's important to protect our planet's ecosystems. After all, we're part of the Biosphere too!
