Answer
[Carbon Dioxide (CO2)]
Explanation
## Step1: Understanding the Concept of Plant Respiration Plant respiration is a process whereby plants absorb oxygen during the night (when photosynthesis is not possible due to lack of sunlight). This oxygen is used to break down stored sugar produced during photosynthesis (performed during the daytime) to provide energy for the plant. Carbon dioxide (CO2) is produced as a waste gas during this process, and it is released into the atmosphere. This process is essentially the opposite of photosynthesis.
