Ecosystems and Populations: A Sustainable Future for Life on Earth

This unit explores how ecosystems are formed by all living and non-living elements, and how organisms evolve or perish under stress, known as the survival of the fittest. As we approach global population limits, climate change will pose serious threats to plants, animals, and humans. Cities like New York City could be underwater in the near future. The vocabulary reference sheet aids in familiarizing students with key terms. The homework provides a sneak peek into ecosystem review focusing on biotic and abiotic factors.
