Part 1:

Sometimes we are interested in the way that organisms are distributed across a particular habitat. Corina Tarnita’s research on the spacing of termite mounds in savanna ecosystems is one example. Watch the video about her research, found at: https://youtu.be/nJGpABrEatc, and then address the following:

• What do you think is the most interesting aspect of Tarnita’s research?
• Discuss how the termite mounds benefit other organisms on the savanna.

Part 2:

Ecology is the study of interactions among organisms and between organisms and their physical environments. Watch the video entitled “Some animals are more equal than others…” found at: https://www.youtube.com/watch?time_continue=1142&v=hRGg5it5FMI. Then address the following two issues:

• Why do you think that many keystone species are predators at the top of the food chain in their respective ecosystems?
• What do you think is the most interesting or significant facet of the video?
