16 neutrons are present in the most abundant isotope.
Explanation:
Phosphorus has 18 isotopes. The most common isotope has mass number (no. of protons 15+ no. of neutrons 16=) 31 .
Estuaries, often reffered to as the nurseries of the sea provide feedind habitats for many aquatic animals and plants. Fish and shellfish commonly eaten in the U.S such as oyesters and Salmon complete almost half of their lifecycles in estuaries. Due to its shallow water,Pamlico estuary especially provides opportunities such as Fishing, crabbing and watersports as well.
We can be able to determine this concept by basing our facts on two concepts. Nutrient Influx, upon reaching the estuarian ecosystem, the nutrients in the presence of sunlight undergoes photosynthesis and produce phytoplanktons. Basically, where there is sunlight, we can assume there is a nutrient influx. Presence of Phytoplanktons will in turn help attract animals such as fish. Also, another contribution of nutrient influx is manure produced by the animals
Sewage treatment plans and fertilizer runoff. Auto emissions of nitrogen, fertilizers applied on golf courses and home gardens can contribute. Some plankton species may produce toxins that might cause these outbreaks
Answer;
-Coral reefs are a very important component of the ocean’s ecosystem because they support sea life, such as crabs and sea turtles. In fact, over four thousand species depend on the survival of the reefs, which are being destroyed by bleaching. More must be done immediately to save the reefs.
Explanation;
-Coral reefs are important for many different reasons aside from supposedly containing the most diverse ecosystems on the planet.
-They protect coastlines from the damaging effects of wave action and tropical storms ( they provide a buffer, protecting our coasts from waves, storms, and floods, helping to prevent loss of life, property damage, and erosion) and also provide habitats and shelter for many marine organisms.
