Let's explore the various tools biologists use to study and monitor the movement of matter and energy in an ecosystem. Food chains, food webs, and ecological pyramids help us understand who eats whom and how changes in a population of organisms can impact predators and prey. Before you get started, don’t forget to print out the OnTRACK Biology Journal.
TEKS Standards and Student Expectations
B(12) The student knows that interdependence and interactions occur within an environmental system. The student is expected to:
