What is primary productivity? Give a brief description of the factors that affect primary productivity.

(N/A) Primary productivity is defined as the amount of organic matter or biomass produced by producers per unit area over a period of time.
Factors affecting primary productivity include:
$1$. Environmental factors: Light,temperature,water,and precipitation significantly influence the rate of photosynthesis.
$2$. Nutrient availability: The presence of essential minerals in the soil or water is crucial for plant growth and biomass production.
$3$. Photosynthetic capacity: The inherent ability of plant species to carry out photosynthesis and their density in a given area determines the total productivity.
