energy _______ and nutrients _______
heat
reason why energy conversions are not completely efficient: energy 'lost' as h______
cellular respiration
reason why energy conversions are not completely efficient: energy 'lost' due to c________ __________
sugars ATP
goal of cellular respiration? break down ______ to make ______
yes
do detritivores have mouths?
no
do saprotrophs have mouths?
saprotrophs
what type of organisms secrete enzymes to to break down dead organisms?
decomposers
what connects all trophic levels?
primary production
what is the amount of light energy converted to chemical energy by autotrophs during a given time period?
photosynthetic
the extent of __________ production sets the spending limit for the energy budget of the entire ecosystem
global energy budget
amount of solar radiation reaching the surface of the earth - limits photosynthetic output of ecosystems
gross primary production
amount of light converted to chemical energy before photosynthesis... like income before taxes
net primary production
GPP (gross primary production - everything) not including the energy used by primary producers for cellular respiration
GPP
NPP + R = ___
NPP
GPP - R = ___
respiration
what is R in the equations GPP - R = NPP and NPP = GPP + R
terrestrial
what type of ecosystem is 2/3 of of the global NPP?
oceanic
what type of ecosystem is 1/3 of of the global NPP?
amino acids nucleic acids
why is nitrogen a nutrient that limits marine production? because it is necessary to make a______ a_______ and n_____ a_____
metabolic
why is nitrogen a nutrient that limits marine production? it is necessary for many ________ processes
phospholipid bilayer/plasma membrane
phosphorus makes up the....
oligotrophic
what type of lake... lots of oxygen, not many nutrients
eutrophic
what type of lake... little oxygen but lots of nutrients
evapotranspiration
the amount of water annually transpired by plants and evaporated from a landscape
production efficiency
___________ ___________ of an organisms is the fraction of energy stored in food that is NOT used for respiration
trophic efficiency
the percent of production transferred from one trophic level to the next
10%
trophic efficiency we will always use in this class
efficient
why is being vegetarian good? it's more e_______
carbon footprint
why is being vegetarian good? less of a c_____ f_________
defenses
factor to keep herbivores in check: plants have natural ________
nutrients
factor to keep herbivores in check: n_______ limit herbivores
abiotic
factor to keep herbivores in check: a________ factors
predation
factor to keep herbivores in check: p_________
competition
factor to keep herbivores in check: intraspecific ___________
interactions
factor to keep herbivores in check: interspecific ___________
globally
nitrogen, carbon, and water cycle all cycle...
phosphorus
which cycle does not cycle globally?
nitrogen fixation
nitrogen cycle: Conversion of nitrogen gas (N2) into nitrate (N03-) (bacteria responsible for this)
Ammonification
nitrogen cycle: When plants and animals excrete waste or die, bacteria convert nitrogen into ammonia
Nitrification
nitrogen cycle: conversion of ammonia to nitrate
Denitrification
nitrogen cycle: bacteria convert ammonia, nitrite and nitrates back into nitrogen gas, nitrogen gas back to atmosphere
seasons
why the up and down of CO2 in the graph that fargo showed us in class? (winter at the top, summer at the bottom) (this is because plants are not doing as much photosynthesis in the winter)
solar energy
what is the water cycle driven by?
okay
practice drawing the water cycle
okay
practice drawing the carbon cycle
lightning
what is also kind of involved in the nitrogen cycle? (idrk how but fargo always talks about it)
atmosphere
phosphorus is not a global cycle because there is no phosphorus in the a__________
weather soil
phosphorus could be a long term cycle because rocks w_________ which slowly adds phosphorus to the s____
vegetation
nutrient cycling is strongly regulated by ___________
