OH.2. Life Sciences: Students demonstrate an understanding of how living systems function and how they interact with the physical environment. This includes an understanding of the cycling of matter and flow of energy in living systems. An understanding of the characteristics, structure and function of cells, organisms and living systems will be developed. Students will also develop a deeper understanding of the principles of heredity, biological evolution, and the diversity and interdependence of life. Students demonstrate an understanding of different historical perspectives, scientific approaches and emerging scientific issues associated with the life sciences.
2.1. Grade Level Indicator: Diversity and Interdependence of Life: Describe the role of producers in the transfer of energy entering ecosystems as sunlight to chemical energy through photosynthesis.
2.2. Grade Level Indicator: Diversity and Interdependence of Life: Explain how almost all kinds of animals' food can be traced back to plants.
2.3. Grade Level Indicator: Diversity and Interdependence of Life: Trace the organization of simple food chains and food webs (e.g., producers, herbivores, carnivores, omnivores and decomposers).
2.5. Grade Level Indicator: Diversity and Interdependence of Life: Support how an organism's patterns of behavior are related to the nature of that organism's ecosystem, including the kinds and numbers of other organisms present, the availability of food and resources, and the changing physical characteristics of the ecosystem.
2.B. Analyze plant and animal structures and functions needed for survival and describe the flow of energy through a system that all organisms use to survive.
