Nitrogen cycle A simple and complete diagram of the nitrogen cycle. The blue boxes represent stores of nitrogen‚ the green writing is for processes that occur to move the nitrogen from one place to another and the red writing are all the bacteria involved. The nitrogen cycle is the process by which nitrogen is converted between its various chemical forms. This transformation can be carried out through both biological and physical processes. Important processes in the nitrogen cycle include fixation

The Carbon Cycle is a complex series of processes through which all of the carbon atoms in existence rotate. The same carbon atoms in your body today have been used in countless other molecules since time began. The wood burned just a few decades ago could have produced carbon dioxide which through photosynthesis became part of a plant. When you eat that plant‚ the same carbon from the wood which was burnt can become part of you. The carbon cycle is the great natural recycler of carbon atoms. Unfortunately

Analysis Questions: Cycles of Matter 1. Explain the role of decomposing bacteria in the carbon and nitrogen cycles. In the carbon cycle‚ decomposing bacteria release carbon from the decaying bodies or waste into the atmosphere. Without them‚ it won’t be able for any organism to access the carbon stored in dead bodies. In the nitrogen cycle‚ decomposing bacteria breaks down animal waste‚ which creates ammonia and nitrate products rich in nitrogen. Although no animals or plants cannot directly

Cardiac Cycle The cardiac cycle describes the coordinated and rhythmic series of muscular contractions associated with the normal heart beat. The cardiac cycle can be subdivided into two major phases‚ the systolic phase and the diastolic phase. Systole occurs when the ventricles of the heart contract. Accordingly‚ systole results in the highest pressures within the systemic and pulmonary circulatory systems. Diastole is the period between ventricular contractions when the right and left ventricles

rock cycle operates. How do rocks metamorphose at destructive plate boundary? Rock cycle is a cycle that describes how rocks are transformed. Igneous rock can change into sedimentary rock or metamorphic rock. Sedimentary rock can change into metamorphic rock or into igneous rock. Metamorphic rock can change into igneous or sedimentary rock. Besides‚ metamorphism at the destructive plate boundaries creates different characteristics of rocks.
