<span>Ozone is simply a molecule consisting of 3 oxygen atoms, which reacts strongly with other molecules. Ozone is created in the stratosphere when high energy uv radiation causes on O2 molecule to split. The free oxygen atoms collide and react with other O2 molecules to form O3.</span>
Production is highest where the solar uv is the greatest eg near the tropics, but once created, the ozone is then circulated towards the poles by the atmosphere. The amount of ozone in the stratosphere can vary with location, season and even day to day climatic conditions.
<span>The process of ozone creation is what makes the O3 in the atmosphere very effective at shielding the Earth from harmful uv radiation, which can cause many biological problems, such as skin cancer. However, due to its high reactivity, the uv found in the tropospher at ground level can aslo be dangerous as a toxic pollutant which is harmful to plants and lung tissue, and is a major cause of smog.</span>
Carbon atoms are converted into metabolites like acetic acid, lactic acid, aldehydes, etc via the action of different bacteria. In the process of fermentation or cellular respiration, carbon atoms are cleaved into three carbon molecule called pyruvate then eventually forming into metabolites.
As diatoms are made from silica this makes diatomaceous earth very abrasive, and so the sharpness enhances the particles as a pesticide. Diatoms are also useful in forensic studies. If a person has drowned then diatoms are able to enter the human body.
Answer:
The species that make up an ecosystem are connected in complex 'food webs' of eater and eaten. When one species disappears, its predators can no longer eat it and its prey are no longer eaten by it. Changes in these populations affect others. Not only that but the ecosystem would be dramatically different or cease to exist altogether.
