Nettoprimäärätuotanto
Nettoprimäärätuotanto, often abbreviated as NPP, refers to the rate at which producers, such as plants, algae, and cyanobacteria, convert solar energy into organic compounds through photosynthesis, minus the energy they expend for their own metabolic processes (respiration). This represents the amount of energy that is available to higher trophic levels in an ecosystem. Primary production is the foundation of most food webs on Earth, providing the organic matter and energy that sustain all other life.
Gross primary production (GPP) is the total amount of organic matter produced by photosynthesis. Respiration (R)
The NPP of an ecosystem is influenced by various factors, including light availability, temperature, water, nutrient
Understanding NPP is crucial for ecological studies as it helps in assessing ecosystem health, carbon cycling,
