Organisms and environments. The student knows that
there are relationships, systems, and cycles within environments. The student
is expected to:
(1) observe the way organisms live and survive in their
ecosystem by interacting with the living and nonliving components;
(A) describe the flow of energy within a food web,
including the roles of the Sun, producers, consumers, and decomposers;
(B) predict the effects of changes in ecosystems caused
by living organisms, including humans, such as the overpopulation of grazers or
the building of highways; and
(C) identify fossils as evidence of past living
organisms and the nature of the environments at the time using models.
