This resource is a 2-minute time-lapse video with accompanying website that compares the impact of fauna (animals such as worms and other insects) on the biodegradation of plant matter. One chamber includes just leaf litter without insects, while another chamber includes leaf litter and insect life. A clear difference can be seen between the two chambers. Other short time-lapse videos are also included on the web page for comparison. This resource is recommended for teaching.
