FLASHCARD QUESTION
Front
Invasive Species Noun
[in-vay-siv spee-sheez]
Back
Invasive Species
A non-native organism introduced to a new environment where it spreads aggressively and causes ecological or economic harm.
Example: This diagram shows how invasive species spread, grouping the pathways into transportation, living industries, and other miscellaneous causes like natural spread.

FLASHCARD QUESTION
Front
Native Species Noun
[nay-tiv spee-sheez]
Back
Native Species
An organism that is naturally found and has evolved in a particular ecosystem, as opposed to being introduced by humans.
Example: The American bison is a native species because it has historically lived and evolved in the grasslands of North America.

FLASHCARD QUESTION
Front
Ecosystem Noun
[ee-koh-sis-tuhm]
Back
Ecosystem
A biological community of interacting organisms and their physical environment, functioning together as a single, complex unit.
Example: This diagram shows how an ecosystem includes all living things (community) and non-living things (water, sand), building up from an individual organism.

FLASHCARD QUESTION
Front
Biodiversity Noun
[bahy-oh-di-vur-si-tee]
Back
Biodiversity
The variety of life within a specific habitat or ecosystem, which is often threatened by the presence of invasive species.
Example: This image defines biodiversity by showing its three levels: genetic (variety within a species), species (variety of different species), and ecosystem (variety of habitats).

FLASHCARD QUESTION
Front
Non-native Species Noun
[non-nay-tiv spee-sheez]
Back
Non-native Species
A species living outside its native range due to human introduction, which does not necessarily cause harm to its new environment.
Example: This image shows a squirrel, a native animal in many places, next to a giraffe, a non-native animal, to explain what a non-native species is.

FLASHCARD QUESTION
Front
Predator Noun
[pred-uh-ter]
Back
Predator
An animal that naturally preys on others for food; invasive species often lack natural predators in their new environment.
Example: This food chain shows how energy moves from a plant to an owl. The owl is a predator because it hunts and eats the mouse for food.
7.
FLASHCARD QUESTION
Front
Ballast Water Noun
[bal-uhst waw-ter]
Back
Ballast Water
Water held in ship tanks for stability, which is a common vector for transporting aquatic invasive species to new environments.
Example: A ship takes in ballast water with local organisms to stay stable after unloading cargo, then releases that water and its organisms in a new location when loading cargo.
