Explanation:
Parathyroid hormone (PTH) is a hormone that is secreted by the parathyroid gland. It is the major regulator of the plasma concentration of calcium ions. It regulates calcium ions in the kidney, intestine and bones.
In the kidney, is involved in the re-absorption of calcium in distal ducts and the renal collecting duct, it is also involved in activating the conversion of 25-hydroxy vitamin D into 1,25-dihydroxy vitamin D (calcitriol).
In the intestine, PTH is involved in the absorption of calcium, by increasing vitamin D production.
In the bone, it helps in regulating calcium levels; when serum calcium level is low, PTH stimulates the activity of the osteoclast, to produce more calcium.
Answer:
the grass is the producer, the snake is the secondary consumer, and the eagle (i think thats what the bird is) is the tertiary consumer
Explanation:
the grass is being produced so that one is obvious
the snake is the secondary consumer because it eats the bunny and the bunny consumes the grass. So the secondary has to be the snake
