Some interesting facts about monarch butterflies is that they; -monarch butterflies do not have lungs -they have a 10 cm windspan and waigh about o.25 to 0.75 grams -monarch butterflies store a poison called cardiac glycosides -depending on the temperature in the summer, the caterpiller stage continues for another 9-14 days I hope this helped a little.
I don't believe that that is true due to the fact you can see soil even if there are no plants in it although im not 100% sure as soil and key components in it may be considered organic
