8. Ecosystem Organization

Summary
Ecosystem Pyramid student workEcosystem Pyramid student work The study of ecology has many layers, ranging from the individual organism, to the population, to the ecosystem, to the planet. It is important for students to know the levels within this hierarchy and to recognize which level they are focusing on at any one time. For the purposes of this activity, students will learn about the different levels (organism, population, community, ecosystem, biome, and biosphere) by choosing an organism and the illustrating a pyramid about that organism. The result is a colorful display of organizational pyramids.
