Answer
Primary productivity :
→ Primary production is defined as the amount of biomass or organic matter produced per unit area over a time period by plants. during photosynthesis.
→ Primary productivity depends on the plant species inhabiting a particular area.
→ It also depends on a variety of environmental factors, availability of nutrients and photosynthetic capacity of plants,
→ Therefore, it varies in different types of ecosystems. The annual net primary productivity of the whole biosphere is approximately 170 billion tons (dry weight) of organic matter.
→ Of this, despite occupying about 70 percent of the surface, the productivity of the oceans are only 55 billion tons.
