classification, biodiversity and conservation Flashcards
morphological species
group of organisms that share many physical features that distinguish them form other species
biological species
group of organism with similar morphology and physiology which can breed together to form fertile offspring and are reproductively isolated from other species
ecological species
all of a population of individuals of the same species living in the same area at the same time

biological classification
organisation of living and extinct organisms into systematic groups based on similarities and differences between species
taxonomic rank
one of the groups used in hierarchal classification systems for organisms eg: species, family, species…..
taxon
taxonomic group of any rank family=elephantidae
kingdom-plantar
taxonomy
study and praise of naming and classifying species and groups of species within hierarchal classification system
hierarchal classification
arrangement of organisms into groups of different ranks. Lowest is species, similar species are grouped together into the next rank genus. Highest rank is domain where many species are grouped together
3 different domains
bacteria archaea eukarya
which domains are prokaryotes
bacteria and archaea
kingdoms of eukarya
protoctists fungi plantae animilia
what sort of nutrition to animals and fungi use
heterotrophic
heterotrophic nutrition
use organic molecules made by other organisms as a source of energy
what type of nutrition do plants have
autotrophic nutrition
how do you know if a protoctist is animal like
no cell walls
what is an animal like protoctist called
protozoa
do fungi ever have cilia
no
plants vs animals specialised cells
plants have much less specialised cells
eukaryotes vs prokaryotes
80s vs 70s ribosome in cytoplasm
membrane vs non membrane bound organelles
cell division
linear vs circular DNA
how do prokaryotes divide
binary fission
what do bacteria and archaeans have in common
no nucleus
plasmids present
no membrane bound organelles
70s ribosomes
cell walls
divide by binary fission
bacteria vs archaeans differences
circular DNA vs Linear DNA associated with histones
peptidoglycan cell wall vs none
mass extinction
when rates of extinction are extremely high
what is mass extinction caused by
major/sudden shift in environment like ace age or asteroid
what causes extinction 5
climate change
competition
introduction of species
human hunting
degradation and habitat loss
why maintain biodiversity 5
moral ethical reasons
ecological reasons
aesthetic reasons
agricultural reasons
economical reasons
how does fossil fuels effect animals
increased co2 levels in air dissolves into large bodies of water like the ocean
co2 forms carbonic acid which dissociates in H+ ions which lowers the pH of the water weakening shells made of calcium carbonate
3 levels of biodiversity
number and range of ecosystems and habitats
number of different species in an ecosystem and relative abundance
genetic variation (diversity of alleles in genomes) within each species
endemic species
found only in a certain area and nowhere else
ecosystem
relatively self contained interacting community of organisms and the environment they live in and interact with. All the biotic and abiotic factors
community
all the living organisms of all species of organisms in a particular ecosystem at a particular time
