How Organism Evolved Physiologically
Organisms adapt to their environment but what happens when an organism’s surroundings and environment change? Physiological ecology is the study and understanding of that mechanism of living organisms and how living things work. Physiological ecology arises with an understanding of the influence of temperatures. Temperature, along with others, is one of the most important factors of Physiological ecology. “Water that is available is another major focus all the organisms that contain water in environments and disburse energy.” ("Adaptation", 2013). Many ecologists studying the importance of water in biological systems focus their research on desert

“The roundworms normally do not have any color and they are extremely short, being less than 5 cm long”, the ("Roundworms", 2013). There are around 15,000 known species of roundworms. “Roundworms own two functional features a tube-within-a-tube body plan and a body cavity. The body cavity is a cavity incompletely lined with mesoderm. This fluid-filled pseudo coelom provides space for the development of organs, and serves as a skeleton”, ("Roundworms", 2013). ("Anatomy Of Animals ", 2012).
The roundworms evolved physiologically to become suited to its environment overtime because how easy they are able to adapt to their surroundings. It does not take a very complicated environment to occupy the roundworms. As you can see from an example of the diagram the shape of the roundworms body has evolved with time making some species of roundworms much larger than others. That way they are able to travel further distances and expand their horizons. Much similar to how snakes move about. There are able to construct their stomach muscles so they are able to wiggle around and move. “Roundworms, also known as the Nematodes, live in soil, the ocean and also fresh water”, ("Roundworms", 2013). Some even live inside and or on animals and plants. Some are even too tiny to see with the naked eye. They make up almost everything in the biosphere which is within the Earth’s ecosystem. Another interesting fact is that how they reproduce and the
