Hi!

Energy will flow through an ecosystem in one <em>direction, </em>from the sun or inorganic compounds to<em> autotrophs </em>and then to various <em>heterotrophs. </em>

The energy flow in an area will be delivering light energy to <em>autotrophs</em>, which make their food from the energy the sun produces. 

The energy flow also delivers energy via inorganic compounds to <em>heterotrophs</em>, which do not make their own food.

Hopefully, this helps! =)
