Matter moves through ecosystems in food chains or biogeochemical cycles
Organism that eats both plants and meat
Process in which water from plant leaves evaporates into the atmosphere
How does the way matter flows through an ecosystem differ from the way that energy flows?
-Energy is passed in one-way direction through the biotic (living organisms) in an ecosystem
