M5: Ecosystem Ecology - Primary Production Flashcards
What is the production of new organic matter?
Primary Production
What is total production by all primary producers?
Gross Primary Production
What are biomass available for consumers?
Net Primary Production
What is the production of biomass by heterotrophs?
Secondary Production
What is a tool used to monitor the isotope to determine the feeding position of the organism?
Trophic Level Graph
What dictate the primary production on land?
Temperature, Moisture, Nutrients, and Precipitation
What is the total amount of water evaporating and transpiring off landscape per year?
Actual Evapotranspiration
What is a single nutrient limits plant growth?
Liebig’s Law of the Minimum
What is relationship of Nutrients and Net Primary Production (PP)?
Directly Proportional
What shape aquatic primary production?
Nutrient levels
What factors in the area will result to highest rate of marine net primary production?
Light availability, upwelling, and breakdown of organic matter
What is the relationship of diversity and productivity?
Directly Proportional
What organisms with shared physiological/anatomical traits?
Functional Groups
What shapes primary production?
Trophic Cascades
Who mentioned that consumer effect ripple throughout food web?
Carpenter & Kitchell (1988)
What are predation effects that alter abundance, biomass, and productivity?
Trophic Cascade
What are the two models of Trophic Cascade?
Top-Bottom and Bottom-Up Model
Where is primary production highest in terrestrial animals?
Areas with Intermediate Grazing Pressure
What is the formula for production?
Production = Ingestion - Egestion - Excretion - Respiration
What happens to the remaining energy from production?
Growth and Reproduction
What is energy transfer from one part of ecosystem to another?
Trophic dynamics
What is amount of energy conserved during trophic transfer?
Ecological effeciency
What is higher trophic levels applies pressure/influence to lower trophic levels?
Top-Down Model
What is lower trophic levels applying pressure/influence to high trophic levels?
Bottom-Up Model
