There are so many examples for that in different areas, like TPT1 experiment carried out in our lab recently.Here's one link: http://www.alfa-chemistry.com/tpt1-cas-167218-46-4-item-290583.htm
This is false!
Carbon is found in many substances!
For example, we breathe out carbon (Carbon dioxide) and as a result, there is an amoung of carbon in the air.
Carbon is also found in many rock types, such as in coal.
Autotrophic.
Dark reaction happens in the photosynthetic process of plants or autotrophs.
(a) A giant redwood tree = Autotroph
(b) A spider = Heterotroph
(c) A rose bush = Autotroph
(d) A mushroom = Heterotroph
(e) A blue whale = Heterotroph
<span>Autrophs are the organisms that have the capacity to form their own food from inorganic substances like the carbon dioxide. </span>
<span>Heterotrophs are the organisms that cannot produce their own food but depends on other animals or plants for their nutritional needs.</span>
