"The term "biogeochemical," tells us that biological, geological and chemical factors are all involved. The circulation of chemical nutrients like carbon, oxygen, nitrogen, phosphorus, calcium, and water etc. through the biological and physical world are known as biogeochemical cycles. In effect, the element is recycled, although in some cycles there may be places (called reservoirs) where the element is accumulated or held for a long period of time (such as an ocean or lake for water)."
Answer:
Explanation: When this study was carried out by Meselson and Stahl, their findings are compatible with the trend expected by semi-conservative analysis, establishing this as the right template. The two parent strands are split as DNA replicates, and each strand acts as a blueprint for a new DNA strand synthesis.
After the first replication, there are two DNA double helices each marked as superscript 14 N slash superscript 15 N. After the second replication, four double helices of DNA are produced. Three of them are marked as 14 N superscript slash 15 N. Two other DNA was marked as 14 N slash superscript 14 N.
Remember that after a round of testing, Meselson and Stahl were able to rule out the moderate template based on the results. At that point, though, they were unable to rule out the dispersive model because that model predicts the same trend as the semiconservative model. But after two trials, the findings made it possible for them to rule out the dispersive design.

Answer:
Due to different climatic condition.
Explanation:
Altitudinal zonation makes possible to grow many different types of crops because of different climatic condition of the region. Each and every plant has different climatic and environmental requirements due to which different plants can be grown on different places where environment is suitable. Some plants needs cool environment so they can be grown on high altitude while some needs warm temperature which can be grown on lower altitudes near the equator.
