Sunlight
Each of the organisms in an ecosystem fills the energy role of (blank),(blank), or (blank).
Producer, consumer, or decomposer
Energy moves through an ecosystem when one organism (blank) another.
Eat
A food (blank) is a series of events in which one organism eats another and obtains energy.
Chain
A food (blank) consists of many overlapping food chains in an ecosystem.
