Answer: Sugar and oxygen
Step-by-step explanation:
The producers are plants that use carbon dioxide and water to convert it glucose. During this process not only glucose is produced, oxygen is also released into the atmosphere as a by-product of this process.
The Oxygen that is released into the environment is the excess oxygen that is not used by the plants for the process of cellular respiration.
The glucose that is made by the plants is used in this form, it is converted into adenosine tri phosphate for the plants to use.
Hence, the correct options are sugar and oxygen.
