Answer: Ecosystem Services
Explanation: Simply put,Ecosystem services refer to all the benefits that man enjoys from his relationship with the ecosystem.Ecosystem services are the benefits that people obtain from ecosystems. Ecosystem services are indispensable to the wellbeing of all people, everywhere in the world. They include provision,regulation and cultural services that directly affect people, and supporting services needed to maintain the other services. From the availability of adequate food and water, to disease regulation of vectors, pests, and pathogens, human health and well-being depends on these services and conditions from the natural environment.
We depend on nature for our survival – without healthy ecosystems, our drinking water isn’t clean nor is the air we breathe. Studies also show that people who spend time in nature tend to be happier than those that don’t. Being outdoor can even act as a natural anti-depressant. With industry and urban sprawl expanding at unprecedented rates, Ecosystem Services attempt to translate the benefits we receive from nature into economic terms so we can better understand the compromise we are making between nature and industrial development.
Medulla oblongata, the lowest part of the brain, is responsible for autonomic functions like ventilation, cardiac conduction, and vomiting.
The brain is a very complex organ that controls about every function of the body. It has three main sections:
1. Midbrain
2. Pons
3. Medulla oblongata or Medulla
The medulla oblongata is situated at the lowest portion of the brain. It connects to the pons on the upper side and the spinal cord on the posterior side. It is primarily responsible for controlling some autonomic functions, some of which are essential for human survival, such as ventilation ( pons work together with the medulla and produce rhythms for respiration) and cardiac function. Other functions involve controlling sneezing, hormonal balance, etc.
