producers
autotrophs --> make their own food
organic molecules
contain carbon
production ways
photosynthesis / chemosynthesis --> bacteria use energy stored in inorganic molecules to produce carbohydrates(Kohlenhydrate)
gross primary productivity
rate at which producers in an ecosystem capture the energy of sunlight by producing organic compounds
biomass
organic material produced in an ecosystem
net primary productivity
rate at which biomass accumulates
consumers
heterotrophs --> can't produce own food
herbivores
eat producers
carnivores
eat consumers
omnivores
eat both producers and consumers
detritivores
eat the garbage
decomposers
brake down complex molecules
trophic level
the organisms position in a sequence of energy transfer
food chain
single pathway of feeding relationships among organisms
food web
interrelated foodchains
energy from one to the other trophic level
