Solution
The correct option is B Net primary productivity
In a food chain, energy stored at the producer level is called as primary productivity. Producer level includes plants and other photosynthetic organisms. Energy stored at the consumer level is called as secondary productivity. Consumer level includes herbivores, carnivores and decomposers. Gross primary productivity is the rate of conversion of light energy into chemical energy of organic molecules in an ecosystem. Net primary productivity is the rate of storage of organic matter except which is utilized for the respiration by plants. In other words, it is the amount of biomass available for consumption by herbivores and decomposers. It is the rate of storage of organic matter apart from that is utilized by consumers. Thus, the correct answer is 'Net primary productivity.'
