what is done on isstvaan after the virus bomb.. 1 little spark ignited the whole planet

also: if you look at how any being is made, it consists of mroe complex compounds than atoms. anorganic matter, which baisscially is what every organic matter consists of,, is not really consumed by tyranids, or else they would not leave behind empty husks of planets. they leave tons and tons of less complex compounds unconsumed.
