Definitions and Context
Adaptation: traits developed over time that help organisms meet their basic needs and survive.
Context: The cardinal's adaptation of a short, strong bill allows it to break open seeds to eat.
Carnivore: a meat eater.
Context: With pointy teeth for ripping flesh, the coyote is a carnivore.
Consumer: an organism that feeds on plants and/or animals.

Fangs: Sharp teeth-like points used by venomous snakes to inject venom into prey
Context: Only venomous snakes have fangs.
Food Web: and interlocking pattern of food chains.
Context: The food web of the wetland ecosystem includes land and water plants, raccoons, egrets, oysters and marsh snakes.
Generalist: organisms that can use a wide variety of food, water sources and living spaces
Context: Raccoons are generalists; they make their habitat in the wild or in your backyard.
Herbivore: a plant eater.
Context: Rabbits eat leafy plants and mice eat the seeds; they are both herbivores.
Inherited trait: an inborn characteristic or behavior that is passed from parent to offspring.
Context: The shape and number of teeth is an inherited trait.
Instinct: an inborn pattern of behavior.

Omnivore: an animal that eats both plant and animal materials.

utilize a very specialized food source or living space and are very
successful as long as the food or space is available.
Context: Endangered species are often specialists that have lost their unique food or homes.
Species: a population of animals that are more or
less alike and that are able to breed and produce fertile offspring
under natural conditions; a category of biological classification
immediately below the genus or subgenus.
Context: Different species of finches have different shaped bills, therefore can eat different foods.
