Ecology Review: Food Chains & Webs, Relationships, Nitrogen & Carbon Cycles, Effects on Biodiversity

Join the Amoeba Sisters in this longer review video as they review food chains, food webs, how energy flows through trophic levels (including the 10% rule), ecological relationships (including parasitism, mutualism, and commensalism), nitrogen and carbon cycles, and examples of how human activity can negatively impact biodiversity (examples include destruction of habitats, invasive species, overharvesting, and greenhouse gas emissions). The video concludes mentioning human efforts that can support and protect biodiversity.
