ecology Flashcards
levels of organisations in an ecosystem
individual population community ecosystem
what is an ecosystem
the interaction between living and non living components
factors that plants may compete for
light space water minerals and ions
factors animals might compete for
mates territory food
intraspecific competition
is competition within a species
interdependence
different species in an ecosystem depending on each other for various recourses
stable community
biotic and abiotic factors in balance so the population sizes remain relatively constant
abiotic factors
non living factors
abiotic factors that may affect an ecosystem
light intensity temp moisture oxygen level
biotic factors
living factors
population
the amount of one living organism in an ecosystem
habitat
an area wich organisms live in
community
populations of different species interacting
what do food chains show
the interaction of different species through transfer of energy
biomass
total mass of living material
what are trophic levels
stages in a food chain
producer
an organism that makes its own food
example of producers
fungi, plants, grass
carbon cycle
the process in witch carbon always travels back into the atmosphere via photosynthesis, respiration, consumption, and combustion
why is the carbon cycle important
carbon contains important molecules such as glucose witch helps living organisms to grow.
biodiversity
different organisms and species in an area
community
interaction between various specires
