Answer 2

Explantation:

The biosphere, also known as the ecosphere, is the worldwide sum of all ecosystems. It can also be termed the zone of life on Earth. The biosphere is virtually a closed system with regards to matter, with minimal inputs and outputs.

or

The biosphere is the space on and near Earth’s surface that contains and supports living organisms and ecosystems. The biosphere is, in the broadest sense, the global ecosystem. The biosphere interacts with the lithosphere, atmosphere, and hydrosphere. The lithosphere is the outer surface of Earth composed of solid soil and rock, the atmosphere is the surrounding gaseous envelope, and the hydrosphere refers to Earth’s liquid water including lakes, rivers, and oceans. In order to study the processes associated with the biosphere, a multi-disciplinary effort has been employed by scientists from such fields as chemistry, biology, geology, and ecology.

KEY TERMS

Energy— The ability to do work. Energy occurs in various forms. The most important ones in biospheric processes are solar (electromagnetic), kinetic, heat (or thermal), and chemical-bond energies.

Global warming— Atmospheric warming caused by an increase in the concentration of greenhouse gases, which absorb infrared energy emitted by Earth’s surface, thereby slowing its rate of cooling. Carbon dioxide and water vapor are particularly important in this respect.
