biodiversity Flashcards
biodiversity
variety of organisms
genetic differences
the ecosystems
species diversity
variety of different species in an area
most basic level
plants to microorganisms
genetic diversity
variations among genetic resources
ecological diversity
an ecosystem= living + nonliving and their interaction
diversity among ecosystems
advantages of biodiversity
supports food security
sustains livelihood through overall genetic diversity
a large number of plants=variety of crops
greater species diversity ensures natural sustainability
healthy ecosystems can withstand disasters
humans have negative effect on biodiversity
prokaryotes
prokaryotic cells , no nucleus
eukaryotes
eukaryotic cells, nucleus+ organelles
features of organisms
nutrition= autotrophic(makes own food), heterotrophic(feeds on living)
cell organisation=unicellular, multicellular
cell type= eukaryotes(genetic material surronded by membrane),
prokaryotes(lacking a membrane)
respiration=aerobic, anaerobic
reprodution
movement
domains of organisms and their kingdoms
archea (archeabacteris)
bacteria(bacteria)
eukarya(protista, fungi, plantae, animilia)
animal kingdom two catergories
vertebrates (warm blood cold blood)
and
invertebrates( with jointed leg without legs)
warm blood ex:
mamallas bird
cold blood ex:
fish reptile
with jointed leg
with 3 or more than 3
without legs
worm like and not worm like
animals characteristics
multi celled
heterotrophic eukaryotes aerobic
sexual reproduction
movement
