User: why over the course of two weeks do the oxygen and co2 levels stay the same?

Weegy: Plants, like all living things, need the proper nutrients to thrive. Unlike animals which can hunt for food, plants need a proper environment to supply them with the basics needed for survival and growth. [ The mechanism that drives plant grwoth is photosynthesis and photosynthesis requires light for energy and CO2 to drive the chemical reactions. Various other elements are needed during photosynthesis to create the carbohydrates which are stored and later used for growth. The process of photosynthesis requires a specific light energy threshold. If the light is not bright enough, photosynthesis will not occur. Beyond that threshold and up to some high light level, photosynthesis will run faster and faster. Depending on aquarium depth and the types of plants, 2 to 3 watts per gallon is normally recommended. It is important to note that if any one of the chemicals required for photosynthesis is in short supply, that shortage will be the limiting factor on the photosynthesis rate. Typical aquariums are deficient in both CO2 and iron (Fe) with respect to optimum levels. Various "trace element" solutions are available to the hobbyist to meet iron and other trace element requirements and CO2 injection can be used to boost the concentration of CO2 in the aquarium. ]

Over the course of two weeks, oxygen and CO2 levels stay the same due to the balance between their production and consumption through processes like respiration, photosynthesis, and natural atmospheric exchange.
