It is the habit of collecting and storing both food and nonfood items that has earned the eastern woodrat is other common name of "pack-rat" or "trade rat". [17] Starting in September, the woodrat will start to forage and store food in its midden for use and survival in the winter. [18]

Food chain in a Swedish lake. Osprey feed on northern pike, which in turn feed on perch which eat bleak which eat crustaceans.. A food chain is a linear network of links in a food web, often starting with an autotroph (such as grass or algae), also called a producer, and typically ending at an apex predator (such as grizzly bears or killer whales), detritivore (such as earthworms and woodlice ...

Nicknames include "packrats" or "trade rats" because of their tendency to hoard things, build large domed dens, and "trade" by dropping then picking up another object for it. Coyotes and other predators will attempt to prey on these rodents by laying waste to the dens, but the sheer volume of material is usually dissuasive. Occasionally, dusky ...
