Ecosystem Flashcards
It is the interaction of living and non-living organism
Ecosystem
A component of Ecosystem Function where it is the amount of biomass produced per unit are by plants during the photosynthesis process.
Primary Production
A component of Ecosystem Function where it is the production of organic matter by the producers by photosynthesis. It is their total organic matter produces and is utilized in respiration
Gross primary productivity
A component of Ecosystem Function where it is the available biomass for heterotrophs from the autotrophs. It is the GPP minus Respiration losses (R).
Net primary productivity
A component of Ecosystem Function where it is the production of organic matter by consumers such as their feces.
Secondary productivity
The raw material used in decomposition.
Detritus
Process of Decomposition where the detritus is broken down into small fragments/particles.
Fragmentation
Process of Decomposition where water-soluble nutrients go down into the soil and precipitated into unavailable salts.
Leaching
Process of Decomposition where bacteria and fungal enzymes further break down the detritus
Catabolism
Process of Decomposition where the organic remains turns into humus, a dark colored amorphous substance that is the reservoir for nutrients of the nature.
Humufication
Process of Decomposition where the humus is further degraded by some microbes and release soluble nutrients that can be taken up by the plants.
Mineralization
Organism that uses 2-10% PAR to produce their own food.
Plants
A specific place in the food chain. Amount of energy decreases at successive trophic levels. Only 10% percent of energy from low to high levels.
Trophic Level
Type of Ecological Pyramid where no. of individuals in a trophic level is increasing downward.
Pyramid of Number
Type of Ecological Pyramid where the dry weight (bio-mass) in a trophic level is increasing downward.
Pyramid of Biomass
