Dear Families,
This week, our class will move from the more general information about the large systems in
nature, biomes, and begin to delve into how individual ecosystems are organized. We will also
investigate the needs of individual organisms and the factors that affect their populations. This
information can be found in Chapter 20 of our textbook. These studies will include the following
topics/objectives:
Living Things and the Environment
GA Performance Standards: S7L4: Students will examine the dependence of organisms on
one another and their environments. S7L4.c: Recognize that changes in environmental
conditions can affect the survival of both individuals and entire species.
