Exotic Species
organisms that have been introduced to an area outside of their normal distribution
Consumer
an organism that generally obtains food by feeding on other organisms
Biodiversity
The variety of life in a particular habitat or ecosystem
Populations
the group of individuals of the same species living in a given area
Communities
an interacting group of various species in a common location
Species
a group of organisms that can reproduce with one another
Ecology
study of the distribution and abundance of organisms
Ecosystem
a biological community of interacting organisms and their physical environment
Biome
an area classified according to the species that live in that location
Biotic
relating to or resulting from living things
Autotroph
an organism that can produce its own food
Decomposers
organism that breaks down dead organic material
Threatened
a species is likely to become endangered
Endangered
very high risk of extinction
Vulnerable
high risk of extinction
Extirpated

Tundra
zone of treeless level or rolling ground found in cold regions
Boreal Forest
forests growing in high-latitude environments
Temperate Deciduos Forest
temperate forest ‘dominated’ by trees that lose their leaves each year
Glasslands Biome
large open areas of grasses
Primary
those that consume the primary producers (plants)
Secondary
those that consume the primary consumers (herbivores)
Tertiary
those that eats the secondary consumers (large predators)
Sustainability

What is meant by the term “Law of Conservation of Mass”?
mass is neither created nor destroyed in chemical reactions
. What is meant by the term “Law of Conservation of Energy”?

What difficulties has the introduction of exotic species done to native species populations in the Great Lakes?
affected the economy, health, and well being of the people that rely on the system
What is meant by the term “Artificial Ecosystem”?
human made structures where biotic and abiotic components are made to interact with each other for survival. It is not self sustaining and can perish without human help.
