bacteria in plant roots
300
Do biomes shift? If so, why?
Yes, climate change, including warming of earth's temperatures will move biomes towards the poles
300
Name 3 compounds (that we discussed) that contain carbon.
carbon dioxide (CO2), glucose (C6H12O6), methane (CH4), etc
300
If secondary consumers receive 950 J of energy, how much energy do producers produce?

Gross Primary Productivity (GPP)
300
What is something the phosphorus cycle and nitrogen cycle both have in common?
both assimilate nutrients into living organisms (whether plants or eventually animals)
400
What are the terms used to describe both: the area where sunlight can reach bodies of water AND the area too deep for sunlight
photic and aphotic
400
Which process is the conversion of soil N (NO3) into nitrous oxide (N2O) gas which returns to atmosphere?
denitrification
400
What 2 organism/aspects are often missing from a food web?
decomposers and sun
400
The net annual primary productivity of a particular wetland ecosystem is found to be 6,000 kcal/m2 per year. If respiration by the aquatic producers is 15,000 kcal/m2 per year, what is the gross annual primary productivity for this ecosystem, in kcal/m2 per year?

500
Which biome has hot, dry summers and mild, rainy winters?
Shrubland
500
What are the equations of photosynthesis and cellular respiration? (include numbers)
photosynthesis: 6CO2 + 6H2O → C6H12O6 + 6O2
cellular respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O

What unit is net primary productivity typically in, regarding carbon production?
(mg-C)/(L-day)
500
What is ammonification?
soil bacteria, microbes & decomposers converting waste & dead biomass back into NH3 and returning it to soil
