Growth and Nutrition of Bacteria All organisms require at least small amounts of carbondioxide, However, some can use CO2 as their sole source of carbon. Such organisms are termed as phototrophs photo-organotrophs autotrophs chemotrophs phototrophs photo-organotrophs autotrophs chemotrophs ANSWER DOWNLOAD EXAMIANS APP
