absorptive heterotroph - An organism (usually a fungus) that obtains its food by secreting digestive enzymes into the environment to break down large food molecules, then absorbing the breakdown products. acidophile - able to live in extremely acidic environments adaptations - inherited aspects of an individual that allow it to outcompete other members of a population that lack the trait; evolve through natural selection Alfred Russel Wallace - came up with a mechanism for evolution simila...
