Carnivorous animals such as frogs, shrews, snakes, owls, skunks, ladybird beetles and mink, kill and eat other animals. These secondary consumers package the sunlight energy as a mixture of proteins and fats we call meat. Predators depend on grazers and browsers and on other predators. Parasititism:
Third-level consumers are any organisms big enough to obtain energy by feeding off lower-level consumers. These are also called tertiary consumers. For example, in a forest ecosystem, snakes eat toads. Heron and large fish, such as bass and walleye, consume smaller fish, frogs and crayfish. Some ecosystems have four or more levels of consumers. Owls, high-level forest predators, go after third level consumers such as snakes and other smaller animals.
