Answer:
Hypothalamus
Explanation:
The portion of the brain that maintains the body’s internal balance (homeostasis).
The hypothalamus is the link between the endocrine and nervous systems.
The hypothalamus produces releasing and inhibiting hormones, which stop and start the production of other hormones throughout the body.
The hypothalamus plays a significant role in the endocrine system. It is responsible for maintaining your body’s internal balance, which is known as homeostasis. To do this, the hypothalamus helps stimulate or inhibit many of your body’s key processes, including:
Heart rate and blood pressure
Body temperature
Fluid and electrolyte balance, including thirst
Appetite and body weight
Glandular secretions of the stomach and intestines
Production of substances that influence the pituitary gland to release hormones
Sleep cycles
The hypothalamus is involved in many functions of the autonomic nervous system, as it receives information from nearly all parts of the nervous system. As such, it is considered the link between the nervous system and the endocrine system

It is then converted into nitrites and then to nitrates by nitrifying bacteria. The denitrifying bacteria then converts nitrates into nitrogen.
