The heart is equipped with four chambers and one-way valves that work with precision to pump blood to and from the body. The heart regulates blood volume to support efficient circulation to the cells, tissues, organs, and systems. It provides oxygen and nutrients to the bodies tissue while also removing metabolic waste from cells to disposal sites. It is ultimately responsible for many homeostatic actives that keep us alive and well. It beats roughly seventy-five beats per minute, which is less than one beat per second.

From the atmosphere, plants use photosynthesis to create energy, which also becomes an energy source for animals that eat the plants. When those animals die, their bodies decay into the soil, which is how carbon is stored into the soil for many years. Deep-water formation can mix the soil and the deep…

  • Biogeochemical Cycles In Biology

    Biogeochemical cycles are the way in which nutrients move through the earths system. It is a pathway for chemical elements to move through biotic and abiotic factors. The ocean contributes largely to these cycles as it acts as a reservoir or sink for the accumulation of nutrients. Even water itself is recycled through precipitation, evaporation and condensation. This is a typical cycle that can be observed for the vital elements of life such as carbon and nitrogen. Microbes are essential to the…
