How does diversity among and between species in a biological system affect the evolution of species within the system?
How does the acquisition of energy relate to the health of a biological system?
How do communities and ecosystems change, for better or worse, due to biological disruption?
How does a disruption of a biological system affect genetic information storage andtransmission?
How do species interactions affect the survival of an ecosystem?
By the end of the unit you should be able to...
Explain how the behavioral and/or physiological response of an organism is related to changes in internal or external environment.
