How do plants and animals in an ecosystem interact with one another and the non-living environment?
Humans can have a major impact on ecosystems.
The student will plan and conduct investigations in which
a) distinctions are made among observations, conclusions, inferences, and predictions;
b) hypotheses are formulated based on cause-and-effect relationships;
c) variables that must be held constant in an experimental situation are defined;
h) predictions are made based on data from picture graphs, bar graphs, and basic line graphs.
The student will investigate and understand how plants and animals in an ecosystem interact with one another and the nonliving environment. Key concepts include influence of human activity on ecosystems.
• During its life cycle, an organism’s role in the community — its niche — may change. For example, what an animal eats, what eats it, and other relationships will change.
• Humans can have a major impact on ecosystems.
• Habitat is the place or kind of place in which an animal or plant naturally lives.
