Read through the list of topics from this unit.
Make sure that you feel confident about each of them before taking the unit test. If there are any topics that you forget or think you need to practice, go back and review those lessons now.identify claims about the cycling of matter and flow of energy among organisms in an ecosystem
• describe how claims about the cycling of matter and flow of energy among organisms in an ecosystem can be expressed as a mathematical relationship
• use the mathematical representation of a food web to describe the transfer of matter and flow of energy between organisms and their environmentuse the mathematical representation of a food web to identify the relative proportion of organisms at each trophic level
• use the mathematical representation of a food web to account for the energy not transferred to higher trophic levels
• describe the inefficiencies in the transfer of matter and energy
• explain how energy from
photosynthesis and respiration drives the cycling of matter and flow of energy under aerobic or anaerobic conditions within an ecosystemWrite a reflection about your learning in this unit. Your reflection should be at least 3 sentences. Use the following sentence starters as a guide.

• The topics in this unit about the cycling of matter and flow of energy among organisms in an ecosystem have helped me understand the interconnectedness of living organisms and their environment.
• Understanding chemosynthesis helps me to explain how certain organisms are able to obtain energy in environments where sunlight is not available.
• Models help me to better understand complex concepts, such as the transfer of matter and flow of energy in a food web, by simplifying them and highlighting important relationships and interactions.
• A mathematical model of a food web helps me to better understand the relative proportion of organisms at each trophic level and the inefficiencies in the transfer of matter and energy within an ecosystem.
