Which of the following is required for photosynthesis to take place?
Which of the following statements about C3 carbon fixation is true?
Which of the following statements about energy and trophic levels is not true?
Moving through trophic levels _______.
Which of the following is true about the efficiency of energy transfer in an ecosystem?
Which of the following best explains why ecosystems need a continual influx of new energy?
Which of the following organisms is located only in the 3rd trophic level of the soil food web?
Explain how entropy relates to the amount of energy that is available in the different trophic levels of a food chain.

Which of the following is not true about energy in ecosystems?
Which of the following is not a direct fate of the energy flowing through photosynthesis?
Question is locked
Ecosystem productivity is principally limited by _______.
Relate the concept of gross and net production to the concept of energy conversion.
Compare the process of carbon fixation in C3 plants to that of C4 plants.
Explain how entropy relates to the amount of energy that is available in the different trophic levels of a food chain.
Entropy increases with every energy transfer between trophic levels. Because usable energy is lost as heat, less energy remains available for work at higher trophic levels.
Why are there different types of carbon fixation?
There are different types of carbon fixation, because plants are located in regions with different conditions. Plants that live in arid regions need to conserve water, while plants that live in more moist conditions will not need to conserve water. Plants that live in dry areas, or areas with higher temperatures have adapted modified methods of carbon fixation to help maximize their efficiency.
Put the following organisms in an aquatic food chain in the order in which energy flows through them, explaining the reason for their placement.small fish, mammal, phytoplankton, zooplankton
phytoplankton → zooplankton → small fish → mammal. Energy flows from producers (phytoplankton) to primary consumers (zooplankton) to secondary consumers (small fish) to tertiary consumers (mammal).
Which of the following is a product of photosynthesis?
Which of the following organisms is located only in the 3rd trophic level of the soil food web?
