Introduction
Students will apply knowledge of estuary organisms to explore food webs and energy flow in an estuary ecosystem using a food pyramid. Students will then read and discuss a scientific article about marine plankton food webs and climate change.

Objectives
Students should understand that:
- Describe three basic trophic levels of an ecosystem: producers, consumers, and decomposer.
- Explain that food energy is lost as it flows through an ecosystem, using a food pyramid to model how there are fewer organisms at each trophic level, supported by larger numbers at the level just below.
- Recognize the potential for far-reaching impacts within marine food webs.
