ecosystems; interactions and dynamics Flashcards
classifying ecosytems
biotic abiotic and limiting factors
components of ecosystems
populations and community
ecosystems
biomes
environments and habitats
abiotic and biotic factors
types of ecosystems
terrestrial and aquatic
environment classification/ naming
abiotic biotic and dominant speciescom
competitive exclusion law
similar species that compete cannot coexist
resource partitioning
organisms feed at different times/ locations to combat competition
niche
the role an organism has in the environment and the conditions it requires to survive
key stone species
controls populations of other organisms of provides critical reasources
intra vs inter
intra: same
intre: diff
collaboration and competition
collab: animals working together
comp: animals competing for resources
mutualism commensalism and parasitism
bb
neutral b
harmed b
preditation
one organism kill another for food
autotrophs
convert inorganic molecules in to organic molecules
heterotrophs
consumers obtain food from others
decomposters
use external digestion to break down food
detrivours
consume dead material
biomass pyramid
measures total dry mass of an organism
can be inverted
number pyramid
total number of organisms
energy pyramid
shows flow of energy from each organism to another
10% rule
90% of energy is loss between trophic levels due to heat and chemical wastes
gross primary productivity
net primary productivity
total energy in producers
total energy available to other organisms
biogeochemical cycles?
how matter travels through biotic and abiotic factors
carbon cycles processes and stores
photosynthesis respiration decomposition combustion
atmosphere terrestrial ocean sediments
