Matter and energy in food webs
Explore how matter cycles between living and nonliving parts of an ecosystem and how energy changes form before leaving as heat. Identify producers, consumers, and decomposers, and describe their roles in moving matter and energy. Understand how food webs model these movements, with arrows showing the transfer from eaten to eater.
