(28 cards)
Characteristic of ecosystem
Sustain life
Vary in size
Energy flows & is directional
Nutrients cycle through
Abiotic terrestrial factors
- sun
- temp
- precip
- wind
- geo location
- fire
- soil
Abiotic aquatic factors
H2O currents
Dissolved nutrients
Suspended particles in H2O
Biotic factors
Plants Animals Microorganism Fungus Bacteria
Biomass
Chemical potential energy
How is everything stored in ecosystems
Stored as biomass
Energy in ecosystems
Each trophic level (in a food chain) contains certain amount of energy
Trophic levels
Where organisms fit in producing/consuming levels
Producers at bottom
Producers are…
Autotrophs
Plants
Phytoplankton
Most producers use
Photosynthesis
Types of consumers
Herbivores
Carnivore
Omnivore
Detritivore
Tertiary consumer
Scavenger
Decomposer
Producers and consumers placed in ecosystem
Producers at bottom
Consumers towards top
Energy flow
Passed in from each consumer/trophic level
Energy efficiency
% of energy transferred from one trophic level to the next
Why is Ecological efficiency low?
Because only a small portion of what is eaten/digested is actually converted into energy
Abiotic/Abiotic
^ CO2 ; v PH
Abiotic/Biotic
Low ph kills fish
Biotic/Abiotic
^ plants -> H2O in soil
Biotic/Biotic
of parasites on rabbit = decline of rabbits health
