Species diversity refers to species richness and how evenly species’ abundance is distributed.

Species diversity refers to species richness and how evenly species’ abundance is distributed. Species richness refers to the number of species in an area. Species abundance refers to the number of individuals per species.

For example, in the image below, we can see that these two communities are composed of the same species, but they differ in regards to species abundance:

A community with twenty different species has greater species richness than a community with only six species. A community with ten species but the majority of individuals in that community are of one specific species does not have an even distribution of species abundance. A community with ten different species and each species has the same number of individuals has a more equal spread of species abundance.

To conclude, the number of species factors into species diversity but also the number of individuals in each species is also considered.

Over time, rain and weathering cause rocks to release phosphate ions and other minerals. This inorganic phosphate is then distributed in soils and water.

Plants take up inorganic phosphate from the soil. The plants may then be consumed by animals. Once in the plant or animal, the phosphate is incorporated into organic molecules such as DNA. When the plant or animal dies, it decays, and the organic phosphate is returned to the soil.

Within the soil, organic forms of phosphate can be made available to plants by bacteria that break down organic matter to inorganic forms of phosphorus. This process is known as mineralisation.

Phosphorus in soil can end up in waterways and eventually oceans. Once there, it can be incorporated into sediments over time.

GRAPHICAL WAYPhosphorus is a chemical element found on Earth in numerous compound forms, such as the phosphate ion (PO43PO43-), located in water, soil and sediments.

The quantities of phosphorus in soil are generally small, and this often limits plant growth. That is why people often apply phosphate fertilisers on farmland. Animals absorb phosphates by eating plants or plant-eating animals.

  • The role of phosphorus in animals and plants

Phosphorus is an essential nutrient for animals and plants. It plays a critical role in cell development and is a key component of molecules that store energy, such as ATP (adenosine triphosphate) , DNA and lipids (fats and oils). Insufficient phosphorus in the soil can result in a decreased crop yield.
