These very same insects help pollinate our crops (including pumpkins), fill the bellies of insect-eating animals (such as bats) and are crucial to the decomposition of other dead organisms (like rats, toadstools and snakes). Decomposition begins several minutes after death with a process called autolysis, or self-digestion. A parasite is an organism that lives on or in another organism, the host, and gets its food from or at the expense of its host.
