Biological systems are composed of multiple levels.
The student is expected to:
(A) describe the interactions that occur among
systems that perform the functions of regulation, nutrient absorption, reproduction,
and defense from injury or illness in animals;
(B) describe the interactions that occur among
systems that perform the functions of transport, reproduction, and response
in plants; and
(C) analyze the levels of organization in biological
systems and relate the levels to each other and to the whole system.
Biological systems work to achieve and maintain balance.
The student is expected to:
(A) describe the role of internal feedback mechanisms
in the maintenance of homeostasis;
(B) investigate and analyze how organisms, populations,
and communities respond to external factors;
(C) summarize the role of microorganisms in
both maintaining and disrupting the health of both organisms and ecosystems;
and
(D) describe how events and processes that occur
during ecological succession can change populations and species diversity.
