1.	Which of the following is a unit of primary productivity?(a) g(b) g^-2 or kcal m^-2(c) kcal(d) mI have been asked this question in exam.I need to ask this question from Ecosystem topic in section Ecosystem of Biology – Class 12
Answer» The CORRECT answer is (b) g^-2 or kcal m^-2 The explanation: The unit of PRIMARY PRODUCTIVITY is the WEIGHT (g^-2) or weight (kcal m^-2). The rate at which the solar energy is converted and stored by the producers PER unit area over a time period is called primary productivity.
