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...

Array - A data structure that stores an ordered list of items, with each item is directly accessible by a positional index. Linked List - A data structure that stores ordered list of items in nodes, where each node stores data and has a pointer to the next node. Bianary Search Tree - A data structure in which each node stores data and has up to two children, known as a left child and a right child. Hash Table - A data structure that stores unordered items by mapping (or hashing) each item ...
