Document Summary
Community a group of interacting plants and animals inhabiting a given area. Predation the consumption of one living organism by another. Predators are distinguished from scavengers and decomposers in that they feed on living organisms. Fact has important implication to the combined dynamics of the predator and prey populations. Parasitism one organism feeds and thrives on another. This organism that is being fed on, is being hindered, or hurt in its development. A relationship in which two organisms live together (symbiosis), one deriving its nourishment at the expense of the other. Transmission from one host to another can be either direct or indirect. Indirect involve an intermediate organism, referred to as a vector. Mutualism both organisms benefit mutually from each other. A relationship between members of two species that benefits both (survival, growth, and/or reproduction) Example: little fish that swim on the sharks and attach.
