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.
Organisms in an ecosystem that first capture energy are called producers. They are typically plants or algae that use sunlight to convert it into chemical energy through photosynthesis. This energy is then passed on to other organisms in the food chain.

Organisms in an ecosystem that first capture energy from the sun are called primary producers or autotrophs. These include plants, algae, and some bacteria that can perform photosynthesis to convert sunlight into chemical energy. This energy is then passed on to other organisms through the food chain.
Colonial organisms first appeared on Earth about 600-700 million years ago during the Ediacaran Period. These organisms were multicellular but lacked specialized tissues or organs.

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).
Scientists believe that the first living cells on Earth were likely anaerobic heterotrophs because early Earth lacked oxygen, and these organisms do not require oxygen for their metabolism. Anaerobic heterotrophs can obtain the carbon compounds they need for energy from organic molecules in their environment, making them well-suited for the conditions of early Earth.

Archaea and Bacteria
The first type of organisms to appear on Earth were single-celled prokaryotic organisms, such as bacteria and archaea. These organisms are among the most ancient forms of life and played a crucial role in shaping the planet's early environment.
Hi, The first of the main sources of energy for earth is photosynthesis, and it is provided by the Sun.
The first eukaryotic organisms on earth were likely single-celled organisms such as protists, which are a diverse group of organisms that have a nucleus and other membrane-bound organelles. These organisms are thought to have evolved around 1.6-2.1 billion years ago.
