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.
biosphere life exsists and extends from the depths of the oceans to the summit of the mountains
Answer:
D
Explanation: Rules of Reflection for Concave Mirrors: Any Incident ray traveling parallel to the principal axis on the way to the mirror will pass through the focal point upon Reflection.
I believe that the answer would be assimilation.
Hope this helps!!
Answer: electron
Explanation: An atom is made up of three fundamental particles: electron, proton and neutron. Electrons have negative charges, protons have positive charges while neutrons have no charge. The number of electrons is equal to the number of protons thus making an atom electrically neutral. Protons and neutrons are located inside the nucleus of an atom while electrons are located outside the nucleus where they revolve round the nucleus in their orbits.
