10.4 ecology Flashcards
phosphrous cycle
plants take in through roots to soil
decomposition
through which phosphorus returns to abiotic reservoir
both cycles go into what
tropic levels
bacteria has a what role in the phosphorous cycle
smaller than nitrogen
cellular respiration comes from where
bodies of water, rocks, soil, atmosphere
photosynthesis
capture light, convert it into chemical energy, and produce carbon to release oxygen
nitrogen cycle
enters by fixing bacteria
how does nitgoren reutrn
through denitfiers
differences between phosphorous cycle and nitrogen cycle
how it goes into the atmosphere
cellular respiration goes through what
animals eating (digestion) or plants use organic carbon for energy
denitrifying bacteria
converts nitrate into N2 gas
bacteria decompose
organic matter into inorganic matter for plants
ammonifying
convert organic nitrogen into ammonium for plants
nitrogen-fixing
converts N2 from the atmosphere into forms and by plants
