The source of energy for most autotrophs is
Other autotrophs
The sun

Answer 1

The source of energy for most autotrophs is the sun. Autotrophs, such as plants, algae, and some bacteria, use sunlight to perform photosynthesis, a process that converts solar energy into chemical energy stored in glucose. There are also some autotrophs that obtain energy through chemosynthesis, utilizing inorganic compounds, but the majority rely on sunlight as their primary energy source.
