We know that temperature controls the rate of respiration and changes the amount of organic matter stored in soils. Based on your knowledge of respiration, would you expect to find more carbon stored in soil in a cool or warm climate? Why?
  1. Cool, because there is less sunlight available, which reduces the rate of photosynthesis
  2. Cool, because microbes in the soil are less active as evidenced through lower rates of respiration
  3. Warm, because microbes in the soil have higher rates of respiration, which releases more carbon into the soil
  4. Warm, because sunlight is readily available, which means plants increase their rate of photosynthesis, leading to more carbon produced
Grade 12 Environmental Science
What best defines carbon assimilation?
  1. The rate at which plants convert carbon dioxide to oxygen.
  2. The frequency with which plants perform photosynthesis.
  3. The amount of carbon dioxide plants convert to glucose.
  4. The rate at which plants convert carbon dioxide to glucose.
