Runoff from fertilizers is a strong contributor to high phosphate levels. At one time, phosphates were also used in detergents.

What is negative feedback interaction between calcitonin and parathyroid hormone?
The parathyroid gland is the major regulator of blood Ca levels. When the Ca levels in the blood decrease, the parathyroid gland releases more parathyroid hormone. This in turn increases osteoclasts which results in more bone breakdown. this releases more Ca into the blood stream. When Ca levels in the blood increase the thyroid gland releases Calcitonin. this decreases the activity of the osteoclasts which in turn decrease the levels of Ca in the blood.
Stream gradient role on stream velocity?
An increase in gradient will generally increase stream velocity.
How is Phosphorus imbalance observed?
Disorders of phosphate metabolism are assessed by measuring serum or plasma levels of phosphate and calcium
What parathyroid hormone increases serum calcium levels?
PTH activates vitamin D in the body, which absorbs calcium and phosphate from foods. It works on the intestine to increase the absorption of calcium. It causes the bones to release more calcium, and causes the kidneys to reabsorb more calcium. This all helps to increase calcium levels.
What does a parathyroid horrmone do?
It controls Calcium and phosphate level.It decrease phosphate level and increase calcium level.
Does a stream's velocity increase or decrease downstream?
increase
Why should we worry about amount of phosphate found in water?
When phosphate is present in very high levels it is toxic to people or animals.
Is calcium phosphate soluble?
No, calcium phosphate is insoluble. This is why calcium levels are kept low inside the cytoplasm (eukaryotic cells).
How low levels of a stream can have harmful effects on wildlife in and around the stream?
GeVy
Why a stream discharge increase?
Stream discharge would increase if additional water enters it, such as from a rain storm or from melting snow.
What happens when stream order increases?
The width of the stream will increase as the order increases
What causes a decrease in phosphate nitrate and silicate levels in a body of water?
The recession does.
