What role do trees play in the Biosphere?

Back

Trees are vital components of the Biosphere as they provide oxygen, habitat, and food for various organisms and help regulate the climate.

Front

What is groundwater and its significance in the Hydrosphere?

Back

Groundwater is water that fills the cracks and spaces in underground soil and rock layers, serving as a crucial source of fresh water for ecosystems and human use.
