Why the Trees Can't Grow Within a Year

Genesis does not give us an indication that noah brought two years worth of food, which would only make the storage problem on the ark bigger. It especially does not suggest that he brought enough animals for the carnivores to eat until a year or two after the flood. Further, not all plants grow within a year. Some, such as trees, take years to grow and bear fruit. So what are you supposed to do if you're a coala and can only eat eucalyptus leaves, but all the eucalypticus trees are dead? Or what are you gonna do if you need to wait multiple years for the fruit trees to grow again and start fruiting
