Question

What system consists of the region where life exsists and extends from the depths of the oceans to the summit of the mountains?

A) geosphere B) hydrosphere C) atmosphere D) biosphere E) lithosphere

Answer 1

The biosphere (from Greek βίος bíos "life" and σφαῖρα sphaira "sphere") also known as the ecosphere (from Greek οἶκος oîkos"environment" and σφαῖρα), is the worldwide sum of all ecosystems. It can also be termed the zone of life on Earth, a closed system (apart from solar and cosmic radiation and heat from the interior of the Earth), and largely self-regulating.[1] By the most general biophysiological definition, the biosphere is the global ecological system integrating all living beings and their relationships, including their interaction with the elements of the lithosphere, geosphere, hydrosphere, and atmosphere. The biosphere is postulated to have evolved, beginning with a process of biopoiesis (life created naturally from non-living matter, such as simple organic compounds) or biogenesis (life created from living matter), at least some 3.5 billion years ago.[2][3]

In a general sense, biospheres are any closed, self-regulating systems containing ecosystems. This includes artificial biospheres such as Biosphere 2 and BIOS-3, and potentially ones on other planets or moons.

Answer 2

The answer is D) Biosphere.

Step-by-step explanation:

The biosphere is the system formed by all living beings on planet Earth and their interrelations, that is, the biosphere is the layer of planet Earth where life takes place. The biosphere is constituted by water, earth and a thin mass of air that includes from the ocean floor to about 10 km of altitude in the atmosphere.
