why did problems with low oxygen levels increasing carbon dioxide Levels develop in biosphere 2? how would you solve these problems ?​

However, it is likely that a contributory cause of oxygen depletion (and CO2 increase) was the high organic matter content of the original soils (see later). Added to these problems, there was some air leakage, estimated at about 10% per annum, between the inside and the external atmosphere.

Explanation:

c is the correct answer!

oxygen is the first element in group 16 (via) of the periodic table. the periodic table is a chart that shows how chemical elements are related to each other. the elements in group 16 are said to belong to the chalcogen family. other elements in this group include  sulfur, selenium, tellurium,  and  polonium.  the name chalcogen comes from the greek word  chalkos,  meaning "ore." the first two members of the family, oxygen and sulfur, are found in most ores.

oxygen is by far the most abundant element in the earth's crust. nearly half of all the atoms in the earth are oxygen atoms. oxygen also makes up about one-fifth of the earth's atmosphere. nearly 90 percent of the weight of the oceans is due to oxygen. in addition, oxygen is thought to be the third most abundant element in the universe and in the solar system.
