Two reasons why it is easy to harvest perlemoen
lianna [129]

Perlemoen is reasonably easy to take available of the ocean and do not really required huge and expensive equipment. The poachers take out millions of rands worth of Perlemoen with relatively simple and cheap equipment such as wet suites, googles and flippers. The most expensive equipment they use are their boats and vehicles. In comparison with the lucrative industry the costs of poaching are low. Perlemoen are often the smaller, younger abalone of the species that are taken because they are quite simply and easier to harvest.

 

1.       The younger perlemoen are found closer to the shoreline and often bunched together and they can get a whole whack of them at one spot.


2.       The strandlopers harvested the perlemoen from the rocks during low tide without the need for diving.

his nutrient is cycled between living things and the soil. Plants absorb this nutrient from the soil and turn it into organic co
djverab [1.8K]

The nutrient is phosphorus

<h3>The phosphorus cycle</h3>

Phosphorus cycles between living components of the earth (biosphere) and the soil (geosphere).

The element's reservoir is mainly the sediments of the ocean and rocks. Phosphorus gets into the soil by weathering of rocks.

Plants are able to pick the element up from the soil and animals are able to get their phosphorus by consuming plants.

When plants and animal die, their body decomposes and the phosphorus in them enters the soil.

Thus, the cycle being referred to in the illustration is the phosphorus cycle.
