Ecology
Productivity
Gross Primary Productivity (GPP)
Production of organic matter during photosynthesis/Time
Net Primary Productivity (NPP) = GPP - Respiration losses
Available or consumption
Secondary Productivity
Formation of organic matter by consumers
Depends on
Plant species
Nutrient availability
Annual NPP of biosphere is 170 million tons
55 mil in oceans
115 mil on land
Decomposition
Fragmentation
Break down of detritus
Leaching
Precipitation of water soluble inorganic nutrients
Humification
Formation of humus
Highly resistant to microbial action
Reservoir of nutrients
Mineralisation
Degradation of humus
Increases if
High oxygen presence
Low amount of lignin and chitin
High amounts of water-soluble stuff and nitrogen
Alkaline soil
Warm and moist environment is provided
Energy flow
Deep sea hydro-thermal vents
Sun
50% is photosynthetically active radiation (PAR)
2-10% captured by plants and used to sustain the entire world
