ME.E. The Living Environment: Students understand that cells are the basic unit of life, that all life as we know it has evolved through genetic transfer and natural selection to create a great diversity of organisms, and that these organisms create interdependent webs through which matter and energy flow. Students understand similarities and differences between humans and other organisms and the interconnections of these interdependent webs.
E.2. Ecosystems: Students describe ways organisms depend upon, interact within, and change the living and non-living environment as well as ways the environment affects organisms.
E.2.a. Explain how changes in an organism's habitat can influence its survival.
E.2.d. Explain how the food of most animals can be traced back to plants and how animals use food for energy and repair.
