The HYPOTHALAMUS is vitally important because of its indirect control over body temperature.

The hypothalamus is an important part of the brain, because of the critical roles it plays in the life of some living organisms including humans. Some of the functions carried out by hypothalamus include: control of hunger, thirst, body temperature, release of hormone, etc. One of its most important functions is maintenance of homeostasis in the body. Homeostasis is the process of maintain constant temperature of the body.  

The normal body temperature is 37 degree Celsius, it is very crucial to maintain this temperature because normal body metabolism will be affected if the body temperature is not at the optimal level. When the hypothalamus senses an increase in body temperature, it sends chemical signals to the sweat glands to produce sweat; sweating brings about the cooling of human system. When the temperature is too low (cold), the hypothalamus send signal to the muscles to produce shivering; the shivering brings about heat and warmth. This is basically the mechanism that the hypothalamus used to indirectly control body temperature and to maintain homeostasis.  

they each offer a fresh glut of resources to the organisms that can arrive and exploit them. as individuals and new species continue to appear, they actively and passively alter the environment. competition for shared resources increases, local abiotic and biotic conditions shift, and the relative abundances of species change accordingly. the process is called ecological succession, and it is one of the earliest and most well-known concepts in ecology.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
