Which of the following statements are incorrect?
(I) Primary productivity depends on the plant species inhabiting a particular area, it also depends on a variety of environmental factors, availability of nutrients and photosynthetic capacity of plants.
(II) Humification leads to accumulation of a dark coloured amorphous substance called humus, which is highly resistant to microbial action.
(III) In an aquatic ecosystem, GFC is the major conduit for energy flow and in a terrestrial ecosystem, a much larger fraction of energy flows through the DFC.
(IV) Primary production is defined as the amount of biomass or organic matter produced per unit area over time period by primary consumers through anabolic process.
(V) The sedimentary cycle are very fast. These include phosphorus, sulphur, potassium and calcium.

Statements IV and V are incorrect and these can be corrected as
Primary production is defined as the amount of biomass or organic matter produced per unit area over a time period by plants during photosynthesis.
Elements such as phosphorus, sulphur, potassium and calcium have sedimentary cycles. These cycles are very slow and less perfect because elements may get locked in the reservoir pool.
