- The mineral nutrients move from the non-living to the living and then back to the non-living components of the ecosystem in a more or less circular manner. This is known as biogeochemical cycling (bio for the living, geo for atmosphere. water, rocks and soil and chemical for the elements and processes involved). We generally call them nutrient or mineral cycles.
- Types of Biogeochemical Cycles: There are two basic types of biogeochemical cycles, gaseous and sedimentary. In the gaseous type of biogeochemical cycle there is a prominent gaseous phase.
- Cycling of carbon and nitrogen represents gaseous biogeochemical cycles. In sedimentary cycles the main reservoir is the lithosphere from which the nutrients are released largely by weathering of rocks. The sedimentary cycle is exemplified by phosphorus and sulphur. Hence statement 2 is not correct.
- When we describe biogeochemical cycle; we often say that a cycle is perfect or imperfect.
- A perfect nutrient cycle is one in which the nutrients are replaced as fast as they, are used up. Most gaseous cycles arc generally considered perfect.
- In contrast, sedimentary cycles are considered relatively imperfect, as some nutrients are lost from the cycle into the soil and sediments and become unavailable for immediate cycling i.e., there are more stages in which short-term or long-term stagnation occurs. Hence statement 1 is correct.
- Most significant of the stagnation stages is sedimentation in oceans and deep continental lakes. So if portions of nutrients. such as phosphorus or sulphur are lost. they are unavailable to organisms for comparatively, longer periods. Human beings have so speeded up the movement of many nutrients that the cycles tend to become imperfect or rather acyclic resulting in too much of nutrients at once stay or too little at another.
