Given below is a specific food chain in a terrestrial ecosystem: Grass Grasshopper Frog Snake Hawk If the Net Primary Productivity (NPP) of the Grass is 5000 J , match the descriptions in List-I with their corresponding values in List-II. List-I List-II A. Energy available to Frog I. 5 J B. Energy available to Snake II. 50 J C. Energy lost to the environment by Grasshopper III. 500 J D. Energy available to Hawk IV. 4

Step-by-step solution

The Net Primary Productivity (NPP) of the producers (Grass, 1st trophic level) is the energy available to the primary consumers (Grasshopper, 2nd trophic level). Thus, energy available to the Grasshopper is 5000 J . According to Lindeman's 10% law, only 10% of the energy available at one trophic level is passed on to the next. The remaining 90% is lost to the environment (through respiration, heat, etc.). Energy available to Frog (3rd trophic level) = 10% of 5000 J = 500 J . (Matches A to III) Energy available to S
