*12.4.5 – Photosynthesis and Cellular Respiration/Energy and Matter

By the end of twelfth grade, students will develop an understanding of matter, energy, and organization in living systems.

Using a balanced equation, describe the process of photosynthesis, including inputs and outputs of material and the role of energy
Explain the role of ATP as an energy carrier
Define the roles of producers, consumers, decomposers, and scavengers in an ecosystem
Outline the levels of organization in living systems
Compare and contrast organic and inorganic compounds, giving examples
Identify the different classes of organic compounds important to living systems, including their building blocks
Using a balanced equation, describe the process of cellular respiration, including inputs and outputs of material and the role of energy
Explain the flow of energy through trophic levels
Explain the dependence (direct or indirect) of most organisms on energy provided by the sun
Compare and contrast aerobic and anaerobic processes
Explain that light has the ability to be reflected, absorbed, or transmitted
Compare and contrast the purposes of photosynthesis and cellular respiration
Construct a sample food chain
Identify biotic and abiotic parts of an ecosystem
State that transpiration is the loss of water from plants to the atmosphere
Describe the benefits of decomposers to ecosystems
Discuss the impact of removing an organism from an ecosystem
Identify how carbon dioxide enters the biotic part of the biosphere
Explain that heat is lost during energy conversions
Compare and contrast the light-dependent and light-independent reactions of photosynthesis
splitting of water
fixing of CO2
Identify the inputs and outputs of glycolysis, specifically the glucose in – ATP out ratio
Identify the end products of anaerobic respiration
Classify yeast as an aerobic or anaerobic organism
