Given below are two statements: Statement I: The primary source of energy in an ecosystem is solar energy. Statement II: The rate of production of organic matter photosynthesis in an ecosystem is called net primary productivity (NPP). In the light of the above statements, choose the most appropriate answer from the options given below.
Statement I is correct but statement II is incorrect
Statement I is incorrect but statement II is correct
Both statement I and statement II are correct
Both statement I and statement II are incorrect
Statement I is correct because, except for deep-sea hydro-thermal ecosystems, the sun is the only source of energy for all ecosystems on Earth . Statement II is incorrect because the rate of production of organic matter during photosynthesis is defined as Gross Primary Productivity (GPP). Net Primary Productivity (NPP) is the Gross Primary Productivity minus respiration losses (R) .
