Primary productivity varies from ecosystem to ecosystem. Explain.

(N/A) Primary productivity is defined as the amount of biomass or organic matter produced per unit area over a time period by plants during photosynthesis.
It depends on the plant species inhabiting a particular area,environmental factors (such as sunlight,temperature,water,and soil nutrients),and the availability of photosynthetic capacity.
Since these environmental factors and the types of vegetation vary significantly across different geographical regions,the rate of biomass production also differs.
Therefore,primary productivity is not uniform and varies from one ecosystem to another.
