The reason as to why there is essentially no waste in the natural world is because; in the natural world, there is essentially no waste since the waste of one organism becomes the nutrients or raw materials for other organisms. Solid wastes are unwanted or discarded material we produce that is not liquid or gas. Mother nature also has her own waste disposal solutions in place for years. In natures one organism's waste is another's feast. Natures clean up crew includes the decomposers, scavengers and the detritivores and also the process of biodegradation.
Heterotrophs contrast with autotrophs<span>, such as </span>plants<span> and </span>algae<span>, which can use energy from </span>sunlight(photoautotrophs) or inorganic compounds (lithoautotrophs<span>) to produce </span>organic compounds<span> such as </span>carbohydrates<span>, </span>fats<span>, and </span>proteins<span> from inorganic </span>carbon dioxide. These reduced carbon compounds can be used as an energy source by the autotroph and provide the energy in food consumed by heterotrophs. Ninety-five percent or more of all types of living organisms are heterotrophic, including all animals and fungi and most bacteria and protists.<span>[4]</span>
Different animals eat different types of food, if there was only one type of animal then they would use up all of their resources consuming one product. Biodiversity provides us with a variety of animals, all of which have different diets, which evens out the amount of products consumed.
