Heterotroph
An organism that cannot make its own food (herbivores depend on plants to get their food)
Autotroph
An organism that makes its own food
Cellular Respiration Equation
C6H12O6+6O2 --> 6CO2+6H2O+ATP
secondary productivity
cellular respiration (primary consumer, heterotroph, herbivore)
Products of Photosynthesis
glucose and oxygen
surplus of photosynthesis to
herbivores
Tropical rainforests in South America and Indonesia (swamps and marshes and estuaries) are most ideal for most net primary productivity because...
most sunlight, precipitation, oxygen from trees
primary productivity
photosynthesis (plants, algae, bacteria --> producers, autotrophs, photosynthesizers)
Glucose
primary product of photosynthesis (C6H12O6)
primary productivity def continued
the rate at which organic material is produced by photosynthetic organisms in an ecosystem
Net Primary Productivity (NPP)
the rate of energy storage by photosynthesizers in a given area, after subtracting the energy lost to respiration
Gross Primary Productivity (GPP)
the total rate of photosynthesis in a given area
Productivity is measured in...
units of energy per unit area per unit time (kcal / m^2 / year)
Reactants of Photosynthesis
water and carbon dioxide
