The biosphere is defined as the area of Earth's surface—including air, land, and water—where life exists. It represents the intricate interactions between all biological entities and their environments. Coined by Eduard Suess in 1875, the biosphere is pivotal in biology and ecology, encompassing all organisms and the conditions they inhabit. Factors influencing the biosphere include Earth's distance from the Sun, its axial tilt (which creates seasons), and changes to natural cycles, such as the water cycle. Explore the delicate balance of life within our planet's biosphere.

Biosphere Area of earth’s surface (air, land & water) in which life can exist
Biosphere Area of interaction between all spheres
The Zone of Life • Best described by Eduard Suess in 1875, who defined it as "the place on earth's surface where life dwells"
The Zone of Life • The biosphere is a core concept within Biology andEcology • Includes all organisms on earth as well as the environments in which they live
Factors that Affect Biosphere • Distance between the Earth and the Sun • tilt of the Earth (seasons) • Changes to natural cycles for example water cycle
