The Flood - Animals and their minimum food requirement

Hello everyone,I stumbled on this site and the first thread I read in detail was this one. Though off topic at times, it has still been a great read regarding the many issues of Noahs ark.I have a few ideas that came up during my reading of this thread and would like to see if they might be addressed. The OP started with the food requirements needed on the ark. Following are a few ideas that loosely follow that basis - I just see it as much more that food and water.1 - How did Noah keep alive the many forms of deadly virus and bacteria species during the one year on the ark? Many of these cannot live without a host, did Noah also provide the host "food" for deadly bacteria and/or viruses? Though I can't name, for sure, an example I am sure there are viruses that kill the host in less than a year (Ebola comes to mind). Two options I can see are to have many hosts or safely contain the species in a lab setting to release once populations have increased post flood. Both options make little sense.2 - Many of the organisms have shorter lifespans than the duration of the flood scenario. Insects especially do not often live a full year. This requires Noah to also have had a breeding program on the ark, or a lab setting to save the DNA for later reintroduction.3 - Genesis 7:20 "Fifteen cubits upward did the waters prevail; and the mountains were covered". The oceans salt content is incredibly important to the discussion. In a salty ocean environment - fresh water species must be included on the ark or all freshwater species would not exist in present day. A counter idea presented is that the oceans did NOT contain saltwater during the time of Noah. I ask two questions then - did all saltwater animals evolve from freshwater animals? Secondly , why do we have multiple saltbeds in the Earth if not for ancient seafloors - How can this be if ancient oceans did not have salt?4 - How is it that the Earths animals all survived on one ark that presumably had a universal temperature? Penguins, polar bears, kangaroos, and camels all coexisted in one temperature range? There are hundreds of examples where animals will die due to the change in temperature by being removed from their environment.5 - Most plants cannot live being submerged in water for a year. The fact that "organisms" require plants, and plants require "organisms" to survive nessesitates that Noah also have live plants on the ark. The simplest example would be a bee needing flowers and vice versa. ( Rain forests contain amazing examples of interdependant species )If one includes these examples, many that scientists have yet to discover, would this not fill Noahs mini-ark ?Fishtanks, labs, airconditioners, greenhouses, and a supercomputer to keep track of it all?"and Noah only remained alive, and they that were with him in the ark."Badly worded perhaps, but I have been awake all night and in dire need of sleep
