Environmental Science Concepts Assessment

The video, led by Anelie Couture, a biology professor and test prep expert, guides viewers through three sample ecology problems from the life science section of the practice general science exam. The first problem involves understanding food chains, heterotrophs, autotrophs, and biomass. The second problem focuses on abiotic factors that directly influence photosynthesis, emphasizing the role of light. The third problem explains the primary cause of ocean acidification, highlighting the impact of increased atmospheric carbon dioxide. The video concludes with a call to action for further study and resources available on study.com.
