Q. Select the true statements I. Gross primary productivity is equal to the net primary productivity minus respiration II. Gross primary productivity is equals to net primary productivity plus photosynthesis III. Net primary productivity is equal to photosynthesis plus respiration IV. Net primary productivity is equal to gross primary productivity minus respiration V. Flow of energy in an ecosystem is unidirectional
A) I, II and III
B) I, IV and V
C) II and III
D) IV and V
Explanation
The rate at which organic compounds are formed in a green plants or in a population of green plants per unit time and area is known as the gross primary productivity. It is usually measured as an increase in the stored energy or an increase in the biomass. GPP is utilised by plants in respiration
