Organisms in Ecosyst

6.12CDEF ORGANISMS, ENVIRONMENTS, & ECOSYSTEMS

TermDefinition
TAXONOMY Branch of science that formally names & classifies organisms by their structure, function, & relationships.
STRUCTURE Arrangement of parts that form a living thing.
FUNCTION What something does.
EUKARYOTIC CELL Cell with a nucleus & membrane-bound organelles.
PROKARYOTIC CELL Cell lacking a nucleus or any other membrane-enclosed organelle.
UNICELLULAR ORGANISM Organism made up of 1 cell.
MULTICELLULAR ORGANISM Organism made up of more than 1 cell & often made up of different types of cells.
AUTOTROPH Organism that obtains its nutrition from simple, inorganic compounds.
HETEROTROPH Organism that's unable to make its own food from simple inorganic molecules.
REPRODUCTION Process by which organisms produce more of their own kind.
SEXUAL REPRODUCTION Reproductive process involving 2 parents whose genetic material is combined to produce a new organism different from themselves.
ASEXUAL REPRODUCTION Method of reproduction that requires only 1 parent.
DOMAINS Highest level of the taxonomic hierarchy; includes 3 groups: Archaea, Bacteria, & Eukarya.
DOMAIN BACTERIA 1 of 3 taxonomic domains; includes prokaryotic, single-celled organisms that lack a membrane-enclosed nucleus & that can be classified by shape.
DOMAIN ARCHAEA 1 of 3 taxonomic domains; includes unicellular prokaryotic organisms, like bacteria, but also share characteristics w/eukaryotes.
DOMAIN EUKARYA 1 of 3 taxonomic domains of organisms; cells contain a membrane-enclosed nucleus.
KINGDOMS 2nd highest level in taxonomic hierarchy; contains 6 groups: Archaea, Bacteria, Protista, Fungi, Plantae, & Animalia.
KINGDOM BACTERIA Kingdom of prokaryotic, single-celled organisms that lack a membrane-enclosed nucleus & can be classified by shape.
KINGDOM ARCHAEA Kingdom of unicellular organisms that are prokaryotic, like bacteria, but also share characteristics with eukaryotes.
KINGDOM PROTISTA Kingdom of single-celled & simple multiple-celled eukaryotic organisms.
KINGDOM FUNGI Kingdom of heterotrophic eukaryotes that reproduce through asexual spores & have chitin in their cell walls.
KINGDOM PLANTAE Kingdom of autotrophic eukaryotes that includes all plants.
KINGDOM ANIMALIA Kingdom of heterotrophic eukaryotes that includes all animals.
BIOSPHERE SUM of all LIVING matter on Earth.
ENVIRONMENT All of the living & nonliving factors in an area.
ABIOTIC FACTORS Factors that are neither living nor produced by living things.
BIOTIC FACTORS Factors that are LIVING or produced by living things.
ECOSYSTEM SYSTEM comprising of ALL the biotic & abiotic FACTORS in an area & all the interactions among them.
HABITAT PLACE where an organism naturally LIVE and GROWS.
NICHE FUNCTION or POSITION of an organism or a population within an ecological community.
SPECIES GROUP of ORGANISMS with similar characteristics that are able to INTERBREED or exchange genetic material.
POPULATION Group of interacting individuals of the SAME SPECIES located in the SAME AREA.
COMMUNITY All of the populations of DIFFERENT SPECIES in a particular area.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
