B.1.44 Describe the flow of matter, nutrients, and energy within ecosystems.

 

Molecules and Cells

7.4.4 Explain that the basic functions of organisms, such as extracting energy from food & getting rid of wastes, are carried out within the cell & understand that the way which cells function is similar in all organisms.

7.4.5 Explain how food provides the fuel & the building material for all organisms.

7.4.6 Describe how plants use the energy from light to make sugars from carbon dioxide & water to produce food that can be used immediately or stored for later use.

7.4.7 Describe how organisms that eat plants break down the plant structures to produce the materials & energy that they need to survive, & in turn, how they are consumed by other organisms.

8.4.5 Explain that energy can be transferred from one form to another in living things.

8.4.6 Describe how animals get their energy from oxidizing their food & releasing some of this energy as heat.

B.1.6 Show that a living cell is composed mainly of a small number of chemical elements - carbon, hydrogen, nitrogen, oxygen, phosphorous, and sulfur. Recognize that carbon can join to other carbon atoms in chains and rings to form large and complex molecules.

B.1.9 Recognize and describe that both living and nonliving things are composed of compounds, which are themselves made up of elements joined by energy-containing bonds, such as those in ATP.

Developmental and Organismal Biology

B.1.17 Understand that and describe how the maintenance of a relatively stable internal environment is required for the continuation of life and explain how stability is challenged by changing physical, chemical, and environmental conditions, as well as the presence of disease agents.

B.1.19 Recognize and describe that metabolism consists of the production, modification, transport, and exchange of materials that are required for the maintenance of life.

Genetics

Evolution

Ecology

7.4.2 Describe that all organisms, including the human species, are part of & depend on two main interconnected global food webs, the ocean food web & the land food web.

7.4.8 Understand & explain that as any population of organisms grows, it is held in check by one or more environmental factors. These factors could result in depletion of food or nesting sites and/or increased loss to increased numbers of predators or parasites. Give examples of some consequences of this.

8.4.4 Describe how matter is transferred from one organism to another repeatedly & between organisms & their physical environment.

B.1.37 Explain that the amount of life any environment can support is limited by the available energy, water, oxygen, and minerals, and by the ability of ecosystems to recycle the residue of dead organic materials. Recognize, therefore, that human activities and technology can change the flow and reduce the fertility of the land.
