They go through the cycle because the matter and nutrients are released into the air cycle into us when we breath go back out but some stays in us so when we decay the soil / bacteria decomposes the nutrients and the cycle starts over again
Respiration in leaves
Oxygen gets diffused in stomata and reaches other cells of the leaves. The carbon dioxide produced in the process of respiration also gets diffused with stomata and moves out of the leaves. Also, respiration in leaves takes places at both day and night time

A geological engineer is a profession that plans and designs structures that are critically affected by geological factors of the earth's crust such as underground water, gradient, rocks and soil, and etcetera.
Explanation:
This kind of engineer is knowledgeable on how to harness the natural gradient of the landscape geography of the region to supply water to the city mainly by gravity. This reduces the power required to pump the water hence reducing the carbon footprint. The engineer also provides the most efficient and least costly way to supply water in the safest way possible.

Molecules brought in and used in the calvin cycle - Carbon dioxide , Ribulose bisphosphate (RuBP)
Molecules produced during the calvin cycle that leave the cycle - a few of the glyceraldehyde-3-phosphate (G3P), NADP+
Molecules used and regenerated within the calvin cycle - most of the Glyceraldehyde-3-phosphate (G3P) , NADPH
<u>Explanation:</u>
Calvin cycle is the light independent reaction that takes place in the stroma of the chloroplast. Calvin cycle uses ATP and NADPH produced during the light reaction. Calvin cycle occurs in 3 steps, they are:
1. Carbon fixation - combines with Ribulose bisphosphate (RuBP) to form 2 molecules of 3-phosphoglyceric acid (3-PGA).
2. Reduction - ATP and NADPH is used to convert 3-PGA into glyceraldehyde-3-phosphate (G3P).
3. Regeneration - some G3P molecule form glucose while other regenerates to form RuBP acceptor.

Magnetic Striping<span>
</span><span>The confirmation of the theory of plate tectonics relies on key insights and scientific experimentation. One of these is the knowledge of the magnetic properties of ocean crust.</span><span>Early in the 20th century, Bernard Brunhes in France and Motonari Matuyama in Japan recognized that rocks generally belong to two groups based on their magnetic properties. One group known as normal polarity has within its mineral composition a polarity similar to the Earth’s magnetic north. The magnetic properties of the other group, called reversed polarity, is the opposite of the Earth’s present day magnetic field. The reason, tiny grains of magnetite found within the volcanic basalt that make up the ocean floor behave like little magnets. These grains of magnetite can align themselves with orientation of the Earth’s magnetic field. How? As magma cools, it locks in a recording of the Earth’s magnetic orientation or polarity at the time of fooling. </span><span>The Earth’s magnetic field is similar to the field generated by a bar magnet with its north end nearly aligned with the geographic North Pole. Yet the Earth’s field is the result of a more complex, dynamic process: the rotation of the planet’s fluid iron rich core. Scientists have known for centuries that the Earth’s magnetic field is dynamic and evolving. The magnetic field drifts slowly westward at a rate of 0.2 degrees per year. </span><span>However, over tens of thousands of years, this field undergoes far more dramatic changes known as magnetic reversals. During this reversal, south becomes north and north south apparently in a geological blink of an eye – perhaps over a period of a few thousands years. What these reversals recorded were stripes on seafloor maps-- stripes of alternating normal and reversed polarities of ocean crust. These “stripes” formed the pattern known as magnetic striping.</span><span>The ocean floor had a story to tell. That story would unfold in the work of three scientists. In 1962, two British scientists, Frederick Vine and Drummond Mathews, and Canadian geologist Lawrence Morley working independently suspected that this pattern was no accident. They hypothesized that the magnetic striping was produced from the generation of magma at mid-ocean ridges during alternating periods of normal and reversed magnetism by the <span>magnetic reversals </span>of the Earth’s magnetic field. </span>
