This continues with tertiary consumers and can include apex predators. Decomposers play an important role in breaking down dead organisms and organic waste, returning nutrients to the environment. There are different types of food chains, including aquatic and terrestrial food chains. Key Takeaways: Food chains show the flow of energy and nutrients in an ecosystem.
