Organization of Matter and Energy Flow
How do plants obtain and use matter and energy to live and grow?
- Create a diagram showing how inorganic carbon is assimilated into organic compounds in plants and overlay this with the flow of energy through the plant.
- Trace the path of movement of inorganic nutrients from soil into the aboveground part of the plant.
- Compare the roles of mycorrhizae and root nodules in the uptake of inorganic materials in plants.
- Identify the two inorganic molecules that are used to produce the majority of a plant’s mass, and indicate their sources.
- Explain how the availability of soil microorganisms has supported or limited the growth of economically important plants.
- For a terrestrial ecosystem, analyze the flow of energy among organisms.
- Explain why plants can grow in a closed terrarium.
- Choose a class of organic compounds other than sugars and, in general terms, explain the carbon and energy sources for synthesis of these materials.
