and there are multiple multiple examples of organisms that are so closely connected we can't consider them totally separate think of lyans formed from fungi and algae and bacteria or the female angler fish one of my favorites whose lure is provided by photosynthetic bacteria and in which the tiny male fuses with the female to become nothing more than an IR removable appendage sharing her bloodstream and depending upon her for nutrients but of course all he really is is a bag of sperm so that she can have young ones and then there are the um the plants
that make no chlorophyll at all and rely on micro isal fungi you know um these fungal networks that creep through the ground you just spoke about for their nutrition or the leguminous plants which have bacteria in their root nodules that fix nitrogen
