1. A research scientist has created a greenhouse that contains only plants (there are no animals present). If this greenhouse is sealed off from the outside atmosphere, how would you predict this isolated system to differ from the outside world?
   The greenhouse receives sunlight through its windows and, at the start of the experiment, has levels of oxygen and carbon dioxide that match the outside world. Which TWO of the following choices would you expect to happen if the scientist checked it again after a week?

   
   For credit, be sure to select TWO answers for this question.

• 1. Carbon dioxide levels in the greenhouse’s atmosphere would decrease.

• 1. Carbon dioxide levels in the greenhouse’s atmosphere would increase.

• 1. Oxygen levels in the greenhouse’s atmosphere would increase.

• 1. Oxygen levels in the greenhouse’s atmosphere would decrease.

1. Which of the following is NOT a role of photosynthesis in ecosystems?

• 1. To provide energy for decomposers by breaking down dead organisms.

• 1. To produce oxygen as the main energy source for all living organisms.

• 1. To synthesize glucose, which is used as a structure molecule for producers and food for consumers.

• 1. To absorb carbon dioxide from the atmosphere and prevent global warming.

How does cellular respiration impact the process of photosynthesis?

• It provides the sunlight needed for photosynthesis

• It releases oxygen that is used in photosynthesis
