Detritivore
100
What would be consumed by a tertiary consumer?
secondary consumer
100
The region of surface, atmosphere, and hydrosphere of the earth that living organisms inhabit
Biosphere
100
Why can't producers use atmospheric nitrogen?
triple bond
100
Which types of organisms in a food chain would be considered herbivores?
Primary consumer
200
What is another word for consumers?
Heterotrophs
200
Typically what percent of solar energy is reflected or passes through producers without being absorbed?
99%
200
The term for how we measure water moving through an ecosystem
Evapotranspiration
200
How do plants carry out transpiration?
Use of stomata on their leaves
200
Net Primary productivity establishes the rate at which ________ is produced over a given time
biomass
300
Process by which organisms create energy from glucose under conditions without oxygen
anaerobic cellular respiration
300
What is the total amount of solar energy that the producers in the system capture via photosynthesis?
Gross Primary Productivity
300
What are the useful forms of nitrogen?
Ammonium (NH4+) and Nitrate (NO3-)
300
What part of the carbon cycle was influenced by the Industrial revolution?
Extraction and combustion
300
How does standing crop differ from productivity?
Standing crop is the amount of energy in a system at a given time, while productivity indicates a rate of energy over time.
400
What formula do we use to get net primary productivity?
NPP = GPP - energy respired
400
If my ecosystem has tertiary consumers making up 10 kcal, how much would the producers have?
10,000 kcal
400
Which part of the phosphorus cycle is considered the slow phase?
Sedimentation, burial, geologic uplift, weathering
400
What two things create atmospheric sulfur?
Fossil fuels and volcanoes
400
Is earth a closed or open system? Explain
Earth is a closed system - energy is allowed to move back and forth but matter is not
500
Write out the complete formula for photosynthesis
500
How do we measure rate of photosynthesis?
We measure the movement of CO2 through an ecosystem?
500
Why is the increased use of fertilizer detrimental?
Nitrogen and phosphorus cannot all be taken up by plants, are moved into lakes and rivers, where algal blooms can happen and then eutrophication
500
What are the seven processes involved in the carbon cycle?
Photosynthesis, respiration, exchange, sedimentation, burial, extraction, combustion
500
What cycles involve assimilation?
Phosphorus and nitrogen
