Unit 1 (Modules 6-7) Flashcards
Producers
Plants, algae, and some bacteria that uses the sun to produce usable forms of energy, such as sugars
Cellular Respiration
The process by which cells convert glucose into energy in the absence of oxygen
What does photosynthesis do to energy
Captures it
What does cellular respiration do to energy?
Releases it
Primary productivity
The rate of converting solar energy into organic compounds over a period of time
Gross Primary Productivity
The amount of solar energy that producers in a ecosystem capture via photsynthesis over a given amount of time (GPP)
Net Primary Productivity
The energy captured by producers in an ecosystem minus energy producers rispire
What is the equation for calculation NPP
GPP - R
What are the units for NPP in energy and biomass
Energy = Kcal/m^2/ year. Biomass= C/m^2/year
Biomass
The total mass of all living matter in a specie area
Standing crop
The amount of biomass present in an ecosystem at a particular time
Primary Producers
Very low efficentinly in converting available sunlight into usable energy
Wavelengths of light that producers can’t absorb are ———-
Reflected
Wavelengths of light that producers can’t absorb are ———-
Reflected
If there is more productivity ————
The more herbivores can be supported
When comparing NPP,
We are measuring the change in a ecosystem
When comparing NPP,

Consumer
An organism that is incapable of photosynthesis and must therefore obtain energy by consuming other organisms ( Hetertroph Herbivore)
Herbivore
A consumer that eats producers (PRimary COnsumer)
Carnivore
A consumer that eats other consumers
Carnivore
A consumer that eats other consumers
Secondary Consumer
A carnivore that eats primary consumers
Tertiary Consumer
A carnivore that eats secondary consumer
Tropic Levels
Transfer of matter and energy; successful level of organisms consuming one another
