Trace elements are important for an organism to survive, and the organism that I can think of is the human body.
Every day we take in trace elements that are for us to survive. The first element that I can think of is iron. When we think of iron we think about it as hard metal that helps hold up buildings or make tools, but iron is needed for the human body also. Most of all iron that we take in is through food and is through the small intestine. Iron is needed in the human body to help us do our day to day activities like walking and talking. Iron is a part of the red blood cells-oxygen delivery system, meaning without iron your cells produce less energy, and it would take more to do the little things like walk. If too much iron is into the body, it could cause intestinal lining problems and can be
deadly.
Another trace element that is in the human body would be Zinc. When you think of Zinc that is like iron, it is a metal and is. Zinc helps stimulate the activity of the body, because it helps with healing the body when it is, and it is needed to help with the development of childhood and pregnancy. In human bodies, males need more Zinc than women, because males releases Zinc in semen, and women pass it on when they are breast-feeding. When a deficiency occurs with Zinc, you will see hair loss or growth problems within the younger age humans.
The final trace element that I will discuss is copper. When we think of copper, the first thing that comes to my mind is a penny, and to have a small amount in the human body is amazing. We use copper in our everyday items, because they are a good metal because it carries and hold electricity. That is what the human body does with copper also, because copper is in the tissues of the human body and is found mostly in the brain and liver. Copper helps transport electrons throughout the human body. If the human body takes in too much copper it could get an upset stomach or diarrhea, but if the human body doesn 't get enough it could lead to death.
In conclusion with these trace elements they can be into the body and many different ways, but the most common way is through food that we eat. When we eat things like beans, wheat, beef, and chicken they contain all these trace elements. How do they contain them? Beans and wheat are and get its nutrition from the sun, water and soil. The same can be for the chicken and cows, which eats grass and organisms that come from the earth. As humans, we recycle the trace elements back to the Earth every time we go to the bathroom. With all trace elements we only need a little to help us survive, but if we take in too much it could be deadly for us. We are all a part of the ecosystem, which means that we need each other to survive. References
