Look at the graph. What change did you notice?

• The decomposers decreased because the line went down.
• The decomposers increased because the line went up.
• The decomposers stayed stable because the line is almost straight.

What caused carbon dioxide to decrease in the air (abiotic matter) of the biodome?

• There were less producers such as trees and plants inside the biodome that were able to photosynthesis.
• There were less producers such as trees and plants inside the biodome that were able to make carbon dioxide during cellular respiration.
• There were less consumers such as people and animals inside the biodome that were able to make carbon dioxide during cellular respiration.
• There were less decomposers such as insects, fungi and bacteria inside the biodome that were able to make carbon dioxide during cellular respiration.
