The secondary consumers of Yellowstone are osprey, bald eagles, bighorn sheep, grizzly bears, coyotes, red-tailed hawks, and bison. Secondary consumers are organisms that get their energy from primary consumers and producers and provide energy for tertiary consumers.

Grasses, shrubs, trees, mosses, lichens, and cyanobacteria are some of the many producers found in a grassland ecosystem. When these plants die they provide energy for a host of insects, fungi and bacteria that live in and on the soil and feed on plant debris.

Tertiary Consumers: Like secondary consumers, their diet may also include some plants. Examples of tertiary consumers include Hawks, Alligators and Coyotes. Hawks feed on small mammals, lizards and snakes. Alligators feed on fish, birds, small mammals and turtles.

Primary consumers: Deer, elk, moose, beavers, bison, otters and bugs. Secondary consumers: Wolfs, bears, fish, birds, fox and badgers.

They are instead called parasites. Some secondary consumers eat both plants and animals. Grasshoppers are primary consumers because they eat plants, which are producers.

The secondary consumers tend to be larger and fewer in number. This continues on, all the way up to the top of the food chain. About 50% of the energy (possibly as much as 90%) in food is lost at each trophic level when an organism is eaten, so it is less efficient to be a higher order consumer than a primary consumer.

Birds are attacked and eaten by other birds, including falcons, owls and eagles. Different kinds of serpents and other reptiles kill adult and baby birds alike. Four-legged predators such as bobcats and weasels are bird-eaters. Some kill and eat fish, other birds, or small animals.

apex predator species at the top of the food chain, with no predators of its own. Also called an alpha predator or top predator.
