Think shorts are from instagram? I have not bothered to look as i don't have an IG account. but the 2nd half of question in can give a better answer.
You can send a dm and they likely will reply. the paper plane icon on right-bottom of screen. or go to their profile and click "chat"
questions can often be rhetorical. meaning you have to look into it and with that increased info, maybe the answer outlined by that person can be more defnitive or more specific.
this is all about rates of change over time of various factors. it's not binary or black and white. memorization isnt the best method for this context, which is what binary thinkers employ. the questions sorrounding plants are more of a "maybe" and "if so" no matter what we prefer it to be.
