Solution
The correct option is B Tropical rain forest
In an ecosystem, energy stored at the producer level is called as primary productivity. Energy stored at the consumer level is called as secondary productivity. Gross primary productivity is the rate of photosynthesis. Net primary productivity is the rate of storage of organic matter except which is utilized for the respiration by plants. Net production is the rate of storage of organic matter which is not used by the consumers. Highest value of net primary productivity in g C m −2 yr −1 of a forest ecosystem is highest in tropical rain forest. Thus, the correct answer is 'Tropical rain forest.'
