Describe how phosphorus moves through the biotic and abiotic parts of an ecosystem
Daniel [21]
Phosphorus is a basic supplement for plants and creatures as particles PO43-and HPO42-. It is a piece of DNA-particles, of atoms that store vitality (ATP and ADP) and of fats of cell films. Phosphorus is likewise a building piece of specific parts of the human and creature body, for example, the bones and teeth. 




Supplements travel through the biological system in biogeochemical cycles. A biogeochemical cycle is a circuit/pathway by which a concoction component travels through the biotic and the abiotic elements of a biological community. It is comprehensive of the biotic factors, or living beings, rocks, air, water, and chemicals.

Explain how the reduction in biodiversity can effect the ecological balance in the dam
hodyreva [135]
<span>Damming a river has a variety of effects on the freshwater ecosystem, more than just altering the flow from A to B.  Dams create calm bodies of water, changing overall temperature regimes and sediment transport, leading to conditions which tend to favour generalist species. Loss of specialist species, particularly endemics, changes the community structure and leads to biotic homogenization.  A dam will withhold sediment in the reservoir, not just decreasing the amount of substrate available to local freshwater species, but even impacting diadromous, estuarine and marine species much further downstream.  The competition between resident species for food and breeding sites will increase as damming isolates populations, and perhaps more importantly, damming completely restricts migratory fish species.  Isolation may lead to decreases in genetic diversity and therefore puts species at greater risk from disease.  All of these effects may be exacerbated by changes in the surrounding land use.  Overall, damming river flow will lead to both a loss of native species, but also an increase in exotic species which are more likely to become established in degraded habitats. For this reason, dams are one of the greatest global threats to freshwater biodiversity.</span>
