An energy pyramid depicts the amount of energy contained in each trophic level, as one progresses from first tropic level to fourth trophic level in this pyramid, what happens to the amount of stored energy?
An energy pyramid depicts the amount of energy contained in each trophic level, as one progresses from first tropic level to fourth trophic level in this pyramid, what happens to the amount of stored energy?
The correct option is B The amount of stored energy decreases.
The amount of energy in each level is represented by a volume and the volumes are stacked from the lowest trophic level (producers) to the highest trophic level (top carnivores). The gross primary production by the producers is 20, 810 cal energy, out of which 11, 977 cal energy is used in the respiration and the net primary production is 8, 833 cal energy. The primary consumers obtain only 3, 368 cal energy from the producers and rest of the energy 5, 465 cal is wasted in their decay. Then out of 3, 368 cal energy which the primary consumers obtain from the producers. The secondary consumers obtain only 383 cal energy from the primary consumers and tertiary consumers (carnivores) obtain only 21 cal energy from the secondary consumers. The energy flow in ecosystem moves in a fixed direction. At the end, the energy reaches to the degraded state.
