Unit 10-14 Flashcards
How did Carlos Linnaeus group organisms in traditional classification?
groups were organized using hierarchy, from largest to smallest, groups were created using similarities between organisms
Taxonomy
The science of classification
List the Linnaeus classification hierarchy in order from largest to smallest
1 Kingdom 2 Phylum 3 Class 4 Order 5 Family 6 Genus 7 Species
Binomial Nomenclature
the system used to name organisms.
Where does an organism get its first & last name? How is it properly?
First = Genus, Last = species:
Genus is capitalized & species is lower case, underlined or italicized
Which organizational tool allows you to group & identify organisms based on similar traits?
The Dichotomous Key
What are the 6 kingdoms of the tree of life?
Bacteria, Archaea, Protista, Fungi, Plantae, Animalia
Clade
A group of organisms that have a single common ancestor
Which organizational tool links organisms by their common ancestors?
cladogram
Traditional Classification
groups were organized using hierarchy from largest to smallest, groups were created using similarities between organisms
Modern Classification
Clade; based on evolutionary relationships rather than any similarities
Ecology
study of interactions among organisms & between organisms & their physical environment
Types of Consumers:
Herbivore: eats plants
Carnivore: eats meat
Omnivore: eats plants & meat
Decomposer: break down dead/decaying material & release energy back to the ecosystem
Detritivore(scavenger): feed on broken down dead/decaying materials to consume energy for themselves
Food Chains
a series of steps in which organisms transfer energy by eating & being eaten
Food Webs
a networking of feeding interactions through a series of connected food chains
Ecological Pyramids
show the amount of energy contained within each tropic level within a food chain or web
(Primary producers make up 1st level, various consumers make up next levels)
Heterotrophs
organisms that must consume their energy (consumer)
-cellular respiration
Biosphere
The entire planet including the land, ocean, & atmosphere & all living things = WORLD
Biome
a group of ecosystems that share similar climates & organisms = COUNTRY
Ecosystem
A group of communities that live in a specific area = STATE
Community
a group of populations that live close by = TOWN
Population
a group of individuals (same species) that live in the same area = HOUSE
Species
a single organism = INDIVIDUAL
Biotic Factors
Biological influences (living= plants & animals)
