Standards For the Unit

S7L4 Students will examine the dependence of organisms on one another and their environments.

a. Demonstrate in a food web that matter is transferred from one organism to another and can

recycle between organisms and their environments.      

b. Explain in a food web that sunlight is the source of energy and that this energy moves from

organism to organism.

c. Recognize that changes in environmental conditions can affect the survival of both individuals

 and entire species.

d. Categorize relationships between organisms that are competitive or mutually beneficial.

e. Describe the characteristics of Earth’s major terrestrial biomes (i.e. tropical rain forest,

savannah, temperate, desert, taiga, tundra, and mountain) and aquatic communities (i.e.

freshwater, estuaries, and marine).
