Wildlife Trophic (Feeding) Levels
Producers • Make or produce their own food (through Photosynthesis). • Examples: trees, plants, flowers
Autotrophs • Self-Feeders – produce their own food. • Another name for producer. • Examples: trees, plants, flowers
Consumers • Organisms that feed on other organisms. • Examples: any animal.
Heterotrophs • Other Feeders – Another name for consumers. • Examples: any animal.
Herbivores • Plant-eaters - animals that feed directly on producers. • Examples: deer, rabbits, cattle, mice.
Carnivores • Flesh-eaters – animals that eat other animals. • Examples: Wolves, Polar Bears, Eagles, Mountain Lion, Sharks.
1st Order Carnivores • Carnivores that feed on herbivores. • Examples: Wolf that eats a deer. Fox that eats a mouse.
2nd Order Carnivores • Carnivores that feed on first-order carnivores. • Examples: Mountain lion that eats a fox. Bears that eat trout.
Omnivores • All-eaters – Eat both plants and animals (herbivores & carnivores). • Examples: Red fox, ground squirrel.
Predators • Carnivores which feed on live animals. • Examples: Owl, tiger, lion, wolf.
Prey • The animals that are eaten by predators. • Examples: rabbits, deer, mice, frogs, birds.
Scavengers • Animals which feed on dead organisms (both plants and animal). • Examples: snails, crayfish, crows, vultures.
Saprophytes • Fungi and bacteria which feed on dead organisms. • Examples: fungi, bacteria.
Decomposers • Organisms which break down (decompose) and feed on non-living organic matter such as dead plants, dead animals, and animal wastes. • Examples: yeasts, molds
Food Chain • Organisms linked together in Feeding Relationships • Example: Grass mouse fox mountain lion
