Primary Productivity
is the rate at which solar energy (sunlight) is converted into organic compounds via photosynthesis by producers/autotrophs over a unit of time in a given area.
Also known as rate of plant growth since photosynthesis translates into plant growth
Gross Primary Productivity(GPP)
Total amount of photosynthesis in a given area
Respiration loss
Plants use up some of the energy they generate via photosynthesis by doing cell. respiration
Net Primary Productivity
The amount of energy(biomass) leftover for consumers after plants have used some for respiration
What does high primary productivity entail?
High PP = high plant growth = lots of food and shelter for animals
Describe the relationship between productivity and biodiversity
Higher biodiversity can enhance ecosystem productivity due to more efficient resource use and stability. Conversely, increased productivity can support greater biodiversity by providing more resources for diverse species.
