There are several theories on how the first organisms on Earth obtained energy. The generally accepted theory is that these organisms harvested organic substances from the primordial soup of energy-rich molecules.
They fed on the autotrophs. The autotrophs made their own food but since the heterotrophs couldn't, they had to eat the autotrophs .

First of all, autographs and heterotrophs are not even closely related. Heterotrophs obtain energy by consuming organic matter of other organisms, either living or deceased. Autotrophs obtain energy by capturing it from sunlight (photosynthesis) or capturing chemical energy (chemosynthesis).

Organisms were first created in the water because the earth's land was never created yet. Water organisms have been the first organisms on earth and it says so in the begining of the bible too. Organisms were created in water because there was no land yet for them to be created on.
Hi, The first of the main sources of energy for earth is photosynthesis, and it is provided by the Sun.
