Unit 5- Productivity

5.1.1. Primary production
The term "production" is the creation of new organic matter by the process of photosynthesis. Primary production is the synthesis and storage of organic molecules during the growth and reproduction of photosynthetic organisms. The core idea is that the new chemical compounds and new plant tissue are produced during photosynthesis. About 10 to 20% of the primary production converted into secondary production. The remaining 80-90% is lost by the consumers in the form of feces.
