rn Which of the following ecosystems will be more productive in terms of primary productivity? Justify your answer. A young forest, a natural old forest, a shallow polluted lake, alpine meadow.
Initially primary productivity will be highest in shallow polluted lake, due to nutrient enrichment of the water body and abundant sunshine. It is however, not sustained and decreases later.
A young forest has a higher primary productivity than an old natural forest. An old natural forest has comparatively smaller amount of productive biomass while a young forest has more of photosynthetic apparatus.
Among these a young forest will be more productive because primary productivity depends on the plant species inhabiting a particular area. A young forest grows more rapidly than old forest hence it has more primary productivity.
A shallow polluted lake and alpine meadow has lower number of producers hence shows lower primary productivity
