What is the equation for photosynthesis?
Light Energy+CO2+H2O -> Glucose+O2
Glucose+O2 -> Light Energy+CO2+H2O
CO2+H2O+H2S -> Glucose+H2SO4
Glucose+H2SO4 -> CO2+H2O+H2S
What is the equation for chemosynthesis?

What do photosynthesis and chemosynthesis have in common?
They both use CO2
They both require an energy source to provide suagrs
They both use the Sun's energy
They both use their sugars to provide metabolic energy via respiration
How are photosynthesis and chemosynthesis different?
Photosynthesis uses chemical energy
In chemosynthesis, the by-product depends on the chemical used
Chemosynthesis uses light energy
In photosynthesis, the by-product is oxygen

What is the formula for energy efficiency?
Gross/Net x 100
Net/100 x Gross
Net/Gross x 100
Gross/100 x Net
What is the formula for energy loss?
P=C+R+F+U
F=R+P+U+C
U=P+C+R+F
C=P+R+F+U
What are some ways that energy can be lost from a food chain?
Death
Heat
Excretion
Egestion
How is energy lost from the Sun to primary producers?
Light energy is reflected off water
Water absorbs light energy
Light passes straight through producer
Wrong wavelengths
Why are pyramids of biomass inverted?
Low biomass of primary consumers to secondary consumers
High biomass of primary consumers to secondary consumers
Low biomass of primary producers to primary consumers
High biomass of primary producers to primary consumers
How do food chains translate into the different pyramids?
Primary consumer -> Secondary Consumer -> Apex Predator -> Primary Producer
Primary Producer -> Primary Consumer -> Secondary Consumer -> Apex Predator
Apex Predator -> Secondary Consumer -> Primary Consumer -> Primary Producer
Primary Producer -> Secondary Producer -> Primary Consumer -> Secondary Consumer
What is the mass of living material in an area?
Kilograms
Pounds
Biomass
Tons
What is the rate of production of biomass per unit area?
Productivity
Photosynthesis
Chemosynthesis
Cellular Respiration
How can productivity be measured?
Using the rate of increase in the biomass of producers
Using the rate of photosynthesis of producers
Using the amount of energy transferred from one organism to another
Using satellite imagery to measure the amount of chlorophyll
What is usually the percentage of efficiency of transfer between trophic levels?
1%
100%
10%
50%
What are some factors that affect photosynthesis?
Nutrients
Light
Salinity
pH
What is secondary production?
The rate of production of new biomass by producers, using the energy gained by eating consumers
The rate of production of new biomass by decomposers, using the energy gained by eating producers
The rate of production of new biomass by decomposers, using the energy gained by eating consumers
The rate of production of new biomass by consumers, using the energy gained by eating producers
What are ways productivity affects food chains?
More productivity -> More biomass
More productivity -> Less biomass
Eutrophication
Less productivity -> More biomass
What is the study of the flow of energy within an ocean ecosystem from the time the energy enters the living system until its degraded to heat and lost?
Forest Energetics
Dessert Energetics
Arctic Energetics
Marine Energetics
