Gross primary productivity (GPP) refers to the total amount of organic matter produced by plants through photosynthesis in a given area over a specific time period. It is a key indicator of the rate at which energy is stored in ecosystems and is crucial for understanding the flow of energy through food chains and the overall productivity of an ecosystem. GPP is influenced by factors such as sunlight, temperature, water availability, and nutrient levels, and is an important variable in ecological studies and climate change research.
