The animal food web consists of four sections: producers, primary consumers, secondary consumers, and tertiary consumers. Producers and decomposers are autotrophs and they support all other trophic levels. Some examples of these would be plants, flowers, nuts, seeds, fruit, phytoplankton, and insects. The next level on the food web are primary consumers, these are herbivores and include organisms like pika, deer, elk, prairie dogs, birds, grasshoppers, zooplankton, squirrels, trout, and frogs. The third level in the food web are the secondary consumers, and they eat the herbivores. Examples of secondary consumers would be, mice, herring, black-footed ferrets, jackrabbits, marten, racoons, ravens, and bison. The fourth level of the web are the tertiary consumers who eat organisms that are considered primary and secondary consumers. Examples of tertiary consumers would be, mountain lions, coyote, bobcats, bears, wolves, and cougars.
