Ecosystems are distinguished by a combination of biotic and abiotic factors. The slideshow first shows images of each terrestrial ecosystem separated by climate zone, and then finishes with mystery ecosystems for students to identify and describe. Ask your students to identify the abiotic factors such as amount of precipitation, elevation, temperature, etc., and how that affects the life zone of of the ecosystem (biodiversity, height of plant growth, etc.).
