PLSC 213 Lecture Notes - Lecture 4: Mixed Grass Prairie, Primary Production, Evapotranspiration
Document Summary
Primary productivity - is the product of photosynthesis by autotrophs and xing it into molecules. Net primary productivity - the product of photosynthesis (total photosynthetic output of autographs in the area - cost of doing business ). The remaining productivity goes into sugars that goes to other functions of the plant. We care about it because it sets the energy budget for the rest of the ecosystem. Productivity if usually higher near cost lines because things are collecting, and. Purple for low productivity, red high productivity where deep water nutrient are upwelling towards the surface as well. River delta, river transport nutrient into the ocean so they will cause upwellings. Although growing seasons are compressed primary productivity will grow. Primary producer - plant and energy moved through the plant can go through a number of pathways. Primary consumers - (herbivores), they are directly consuming the primary producer.
