Answer:
When the level of release of carbon dioxide during respiration and use of carbon dioxide during photosynthesis this results in a compensation point. At compensation point the net available carbon dioxide to phototrophs becomes zero. As, carbon dioxide is the chief ingredient for photosynthetic products like glucose and oxygen. These products are used up during the process of respiration. When the rates of two processes photosynthesis and respiration becomes equal. Phototrophic organisms will not be able to compensate for lack of carbon dioxide levels. Phototrophs will not be able to produce their food in the form of glucose and hence will not be able to respire too. This will result in lack of overall available food from phototrophs and lack of available oxygen for respiration. This will result in decline of organisms on earth.
All of these components are reservoirs of carbon. The cycle is usually discussed as four main reservoirs of carbon interconnected by pathways of exchange. The reservoirs are the atmosphere, terrestrial biosphere (usually includes freshwater systems), oceans, and sediments (includes fossil fuels).
The reason that organisms cannot produce populations of unlimited size is that
A. interactions between organisms are unchanging
B. there is no carrying capacity on Earth
C. species rarely compete with one another
<u>D. the resources of Earth are finite</u>
If thousands of glucose molecules were bonded together with equal numbers of sucrose molecules, the resulting substance could be described as a polysaccharide. They are <span>polymeric carbohydrate molecules composed of long chains of monosaccharide units bound together by glycosidic linkages.</span>
