1.	What is the rate of storage of organic matter not used by consumers called?(a) Gross primary productivity(b) Net primary productivity(c) Secondary productivity(d) Net productivityI had been asked this question in class test.This intriguing question comes from Ecosystem topic in section Ecosystem of Biology – Class 12
