Verified step by step guidance1
Understand the concept of energy flow in an ecosystem: energy typically enters the ecosystem from an external source and moves through different trophic levels.
Identify the primary source of energy for most ecosystems, which is the Sun, providing energy in the form of sunlight.
Recognize that producers (autotrophs) such as plants and algae use sunlight to perform photosynthesis, converting solar energy into chemical energy.
Note that energy flows from producers to consumers and decomposers, but not in the reverse direction; energy does not flow from decomposers or consumers back to producers or the Sun.
Conclude that the direct flow of energy in an ecosystem is from the Sun to producers (autotrophs).
