Question 40

How does the biosphere support life on Earth?

Answer 40

The biosphere supports life on Earth by providing the necessary conditions for living things to survive and reproduce. It includes the atmosphere, hydrosphere, and lithosphere, which interact to create a suitable environment for life. The biosphere also provides resources such as food, water, and oxygen for living things.
