taxonomy
the scientific study of how living things are classified
species
a group of organisms so similar to one another that they can breed and produce fertile offspring
invertebrate
lacking a backbone or spinal column
vertebrate
having a backbone or spinal column
herbivore
plant-eating animal
carnivore
any animal that feeds on flesh
omnivore
eats both meat and plants
predator
animal that hunts and eats other animals
prey
an organism that is killed and eaten by another organism
kingdom
second largest taxonomic group; there are six - animalia, plantae, protista, eubacteria, archaebacteria, fungi
domain
the broadest taxonomic group, larger than kingdom; three exist - bacteria, archaea, eukaryota
Archaea
domain maid up of prokaryotes most of which are known to live in extreme environments that are distinguished from other prokaryotes by differences in their genetics and in the makeup of their cell wall
bacteria
domain made up of prokaryotes that usually have cell wall and that usually reproduce by cell division: no nucleus
Protista
eukaryotic organisms that are either single celled or multi celled organisms that lack complex organization
Fungi
Kingdom composed of heterotrophs; many obtain energy and nutrients from dead organic matter
eukarya
domain made up of all eukaryotes: this domain aligns with the traditional kingdoms Protista, Fungi, Plantae, Animalia
plantae
kingdom made up of complex, multicellular organisms that are usually green, have cell walls made of cellulose, cannot move around and use the sun's energy to make sugar by photsynthesis
anamalia
kingdom made up of complex, multicellular organisms that lack cell walls can, can usually move around and quickly respond to their surroundings
ecology
study of interactions of living organisms with one another and their environment
population
group of organisms of the same species that live in a specific geographic area
community
all the populations of species that live in the same habitat and interact with each other
ecosystem
community of organisms and their abiotic factors
biome
large region characterized by a specific type of climate and certain types of plant and animal community
niche
role of a species in its community, including use of its habitat and its relationships with other species
habitat
the place where an organism usually lives
