Sci 115 week 10 discussion

Our focus this week is on ecology. 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:

2. What do you think is the most interesting or significant facet of the video?
