Question

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.

Answer 1

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.
