Here's what makes up the biosphere:

* Atmosphere: The layer of gases surrounding the Earth, providing oxygen for breathing and protecting us from harmful radiation.

* Hydrosphere: All the water on Earth, including oceans, lakes, rivers, groundwater, and ice. Water is essential for all life.

* Lithosphere: The Earth's crust and upper mantle, providing land for plants and animals to live on, and minerals for nutrients.

The biosphere is a complex and interconnected system, where all living organisms interact with each other and their environment.
