Using Explain Everything, Google Drawing, ThingLink, or another web tool, create a video that shows you drawing and labeling a model of how dung beetles or carrion beetles move matter in an ecosystem, including how they feed on matter and how that matter is broken into smaller pieces. Upload that video to YouTube and embed the video on your blog post.
