Most of living things on earth have the ability to survive on climatic variation, thus possess a vital characteristic which can perform that capability. Unfortunately, some animal only can live in specific environments because lack of adaptation ability in their genes. A regular frog only can survive in humid ambience because of their moist skin. If the frog is placed on a dessert, the probability of survival of the frog is very low and might end up dead. These phenomena not actually because of the frog’s dried skin, but the internal body system of the frog cannot function well in a hot and dry atmosphere. According to Akin (2011), the important aspect for every species to survive in various categories of biomes and aquatic environment is the capability to modify to external environment change and control a consistent internal body system and regulation. Homeostasis is a regulation of internal body environment through a feedback mechanism consist of a specific organ structure of the nervous and endocrine system (Bailey, n.d.). Examples of homeostatic processes in the body consist of temperature regulation, pH maintenance, fluid and electrolyte balance, blood pressure, and respiration. In this essay, we only cover the regulation of temperature or thermoregulation on animals. There are 4 distinct types of thermoregulation which include poikilotherm, homoeotherm, ectotherm and endotherm. Thermoregulation actually is the most vital and distinguishable form of homeostasis. Each type of enzymes within cells required optimal temperature internally to remain functional (Shmoop Editorial Team, 2008).
The first types of thermoregulation are poikilotherm. Poikilotherm is termed as an organism which can regulate its body temperature accordin...

...animals except mammals and birds are ectotherms” (p. 286). To control their body temperature, some of the ectothermic animals adapt to a certain behavior. Lizard, a reptile, will find a sunny place and then strecth out for largest exposure to sunlight. If the environment become too warm, they will shift between the sun and shade (Starr, 2003). Example of ectothermic animals are snakes, lizards and frogs.
In conclusion, the four types of thermoregulations that was discussed are poikilotherm, homeotherm, endotherm, and ectotherm. Each of them have their own unique characteristics and their adaptation are mostly regulated by their environment. This is one of the most preferred examples for homeostatis process because it allows that certain organisms to survive in their harsh environment so that their genomic information can be passed from their generation to the next.
...ightly to allow some air to pass underneath it. Snakes can regulate their temperature by placing different proportions of their bodies in sun or in shade. The variations are numerous, but the end result is the same ¡V some degree of temperature regulation in reptiles.
The alternate hypothesis is that there exists an optimal temperature for catecholase enzyme in which the catecholase enzyme can operate with the highest possible activity.
The Arctic conditions are extreme; they consist of sub-zero temperatures, heavy snow, strong winds and ice. To survive these conditions animals must keep a constant body temperature to maintain the optimum temperature for essential chemical reactions to take place. If a living cell cools to a temperature below 0°C then ice crystals can form which will puncture the cell membrane causing the cell to burst. If a living cell reaches temperatures above 45°C then the proteins (including enzymes) are denatured; therefore no longer work. This means that the thermal limits for life are 0-45°C. Animals must regulate their body temperatures' between these bounds to survive. Mammals and birds stay closer to the upper bound.
In our body’s we have thousands upon thousands of cells that work together to maintain the whole structure. Although cells accomplish different roles, they all are comparable in their metabolic conditions. Preserving a continuous inner environment with what the cells require to survive like sugar, minerals, oxygen and waste removal is essential for the cells and host well-being. The diverse process that the body controls its inner environment are referred to as homeostasis. Homeostasis refers to maintaining a stable environment in reaction to environmental changes. The body’s inner environment requires constant observation to maintain a stable inner environment this way if conditions occur they can be adjusted. Homeostatic regulation is the adjustment of systems in the body. “Homeostatic regulation involves three parts or mechanisms: 1) the receptor, 2) the control center and 3) the effector.” (Wikibooks, para. 2)

Homeostatic mechanism use feedback loop. The detection - correction or feedback systems that the body uses to maintain homeostasis are constantly detecting internal or external conditions. These homeostatic mechanisms then evaluate the conditions to determine whether or not they represent any deviations from the normal. If conditions are outside of the optimal functioning range, the mechanisms take corrective action to bring the body back into balance. A good example of a negative feedback mechanism is a home thermostat (heating system). The thermostat contains the receptor (thermometer) and control center. If the heating system is set at 70 degrees Fahrenheit, the heat (effector) is turned on if the temperature drops below 70 degrees Fahrenheit. After the heater heats the house to 70 degrees Fahrenheit, it shuts off effectively maintaining the ideal temperature.

Although the experiment produced varying results amongst the pairs of test tubes in each of the water temperatures, the Mean calculations proves that the temperature rising will increase the amount of kinetic energy in the movement of the Phosphate and Lipids in the cell membrane as well as breaking the hydrogen bonds of the proteins in the cell membrane,
As the following report demonstrates, some species are adapting to climate changes while many others are not. In some cases, laboratory experiments have lead to the conclusion that certain species can or cannot adapt and evolve. This research is not sufficient to make definitive statements regarding what will happen to species if temperatures and sea levels continue to rise.
The cricket will experience an increase in metabolic rate when subjected to physical stress similar to the response of (Blaptica dubia) cockroach. The cricket will also show an increased response as the (Blaptica dubia) cockroach when cold, hot, and lethal hot temperatures are applied.

The ecological consequences of global climate change are expected to be drastic although not much is known as to how individual species will react to these changes. Irrespective of the causes of climate change, whether anthropogenic or natural, it is imperative that we address these concerns, as they will have widespread impacts on the human species, both directly and indirectly through forcings on other species. The climate is not expected to shift evenly and the ways in which certain species adapt or migrate due to these changes could be erratic and unpredictable. The rate at which the earth’s climate is currently changing is unprecedented and has not been seen in the past 450,000 years. Although many species have simply migrated northward or vertically up mountainsides to escape warming habitats, others do not have this luxury or cannot migrate fast enough to survive. The earth’s temperature has risen by over one degree Fahrenheit over the past century, based on land and sea level measurements. The temperature is expected to continue rising at a faster pace over the next century, possibly increasing by as much as seven degrees Celsius. In comparison, the earth’s average global temperature was only twelve degrees cooler than it is now during the last great ice age. A vast majority of species now living do so within a narrow spectrum of temperature ranges and will not be able to adapt to a warming climate on such a large scale. If humans are the cause of a warming climate we will ultimately be responsible for the destruction of millions of species.
Physiological theory is divided into two categories. Homeostasis refers to the body ‘s automatic system to maintain normal state. In order for the body to maintain normal state, it has to have water content, sugar level, salt content, protein, fat content, calcium content, and constant temperature of the blood. Another part of the physiological needs is the appetite which relates to the need of the body. When the body lacks certain chemical , then the body will have certain appetite for that need. All physiological needs are not homeostasis . The other needs are desire , sleep, and maternal need in animals. Physiological needs is considered to isolated because they are localizable and somatically (Shafritz&Hyde, 2012, p.114).
In many parts of the world, ecosystems’ temperatures begin to rise and fall to extreme levels making it very difficult for animals and plants to adapt in time to survive. Climate has never been stable here on Earth. Climate is an important environmental influence on ecosystems. Climate changes the impacts of climate change, and affects ecosystems in a variety of ways. For instance, warming could force species to migrate to higher latitudes or higher elevations where temperatures are more conducive to their survival. Similarly, as sea level rises, saltwater intrusion into a freshwater sys...
