Life Cycles and Survival in an Ecosystem

3rd Grade - Life Science - NGSS

Students continue to explore the balance in an ecosystem and the dependency of organisms within the system. They develop models of the life cycles of a variety of organisms. Students determine how some organisms survive well where others do not. They compare data from fossils to modern organisms.
