Rats are eaten by foxes. Foxes are secondary eaters in the food cycle, and rabbits are the major herbivores. Omnivores and carnivores are both examples of secondary consumers. As an omnivore, the fox consumes a variety of foods, unlike the rabbit, which only consumes plants.
A rabbit and a red fox are two other instances of predator-prey interactions on a food chain. Trophic levels, such as producers, primary consumers, secondary consumers, tertiary consumers, and decomposers, make up a food chain. A food chain can show how connected the various creatures are in an ecosystem.
For instance, grass is a producer and is consumed by rabbits as their main source of food. Red foxes prey on bunnies as secondary consumers, and coyotes prey on fox cubs as a tertiary consumer.
Additionally, the food chain displays every food that an animal can consume. Foxes can consume berries, fruits, birds, insects, rodents, and a variety of other small mammals in addition to rabbits.
