When the primary productivity is calculated in terms of total plant community of an ecosystem , it is called............ Productivity.

Explanation

**Step-by-Step Solution:**

1. **Understanding Primary Productivity**: Primary productivity refers to the rate at which producers (like plants) in an ecosystem convert solar energy into chemical energy in the form of biomass. This is a crucial process as it forms the basis of the food chain.

2. **Identifying Producers**: In an ecosystem, producers are typically plants or phytoplankton that perform photosynthesis, using sunlight to synthesize food from carbon dioxide and water.

3. **Defining Community Productivity**: When we calculate primary productivity by considering the total biomass produced by a group or community of plants within an ecosystem, we refer to this as community productivity.
