Heterotrophs came first because they could live off the minerals in the oceans (Heterotrophs are just organisms that take their source of energy from somewhere else - minerals do count). Autotrophs, however, could not have lived first because the ozone layer was not formed, and taking in the sunlight would have been the same as taking in harmful UV radiation that would have killed the autotrophs. The cyanobacteria (which are heterotrophs) were the ones that first helped create the ozone layer.
Actually, Cyanobacteria aren't heterotrophic. This WRONG answer led me cramming for our debate about Autotrophs vs. Heterotrophs. If you want to know about which came first, either search about primordial theory by A.I Oparin or go to http://leiwenwu.tripod.com/

Heterotrophs obtain energy by consuming other organisms, while autotrophs make their own energy through processes like photosynthesis or chemosynthesis. Essentially, heterotrophs rely on external sources for energy, while autotrophs are self-sufficient in energy production.
Autotrophs are able to produce their own food using their surroundings and do not require an additional source of food. Heterotrophs must find outside sources of nutrients, as they cannot produce their own.
Dogs are heterotrophs, which means they obtain energy by consuming other organisms. They rely on food sources such as meat, vegetables, and grains to provide the necessary nutrients to sustain their metabolism and growth.
No, a lion is not an autotroph. Lions are heterotrophs, meaning they obtain energy by consuming other organisms. Autotrophs are organisms that can produce their own food through photosynthesis or chemosynthesis.
Actually, an organism that makes its own food is called an autotroph. Autotrophs are able to produce their own organic compounds from inorganic sources using sunlight or chemical energy. Heterotrophs, on the other hand, rely on consuming other organisms for their energy and nutrients.
autotrophs

Heterotrophs.
The answer is ......... Heterotroph!!!!!!!!!!!!!!!!!!!
Heterotrophs :D
Humans are heterotrophs Plants are autotrophs
heterotrophs and autotrophs depend on each when heterotrophs obtain food by decomposing other organisms. To live, all organisms, including plants, must release the energy in sugars and other compounds.
Autotrophs, but not heterotrophs, can nourish themselves beginning with CO2 and other nutrients that are inorganic.
No, detritivores are heterotrophs.
heterotrophs
Are called heterotrophs.
