1. Show slides or films of different biomes, since it is very hard to appreciate the diversity of these areas without seeing pictures. Note the differences in the characu Ÿßstics of each.
2. Discuss why it would be reasonable to call the deep ocean a desert area.
3. Discuss the concept of the food chain (or web or pyramid) in the ocean or lake environment and how the plankton are the base of the nutritional interactions. Mention also how they are important in the generation of oxygen and the removal of carbon dioxide from the air.
4. Compare the different biomes according to altitude
and latitude with respect to the diversity of organisms. Explain
‚À organisms that fit into the same niche on two adjacent mountains
are more likely to be different species than are organisms spread
over a broad range of latitude. (The reason for this would be
the isolation imposed by altitude that is not present with latitude.)
