Final answer:
Temperature and CO2 levels affect oxygen production in photosynthesis. The rate of oxygen production is directly related to the rate of photosynthesis.
Step-by-step explanation:
A) Temperature affects oxygen production in photosynthesis. As temperature increases, the rate of photosynthesis also increases up to a certain point. This is because temperature affects the activity of enzymes involved in photosynthesis. However, excessively high temperatures can denature the enzymes, leading to a decrease in oxygen production.
B) CO2 level affects oxygen production in photosynthesis as well. Carbon dioxide is a necessary reactant for photosynthesis, and an increase in CO2 levels can stimulate photosynthetic activity, leading to increased oxygen production. Conversely, a decrease in CO2 levels can limit photosynthesis and result in decreased oxygen production.
C) The rate of oxygen production is directly related to the rate of photosynthesis. As photosynthesis occurs, oxygen is released as a byproduct. Therefore, a higher rate of photosynthesis will result in a higher rate of oxygen production.
