Which statement describes how heterotrophs depend on autotrophs for survival?
Autotrophs supply oxygen for respiration.
Autotrophs produce carbon dioxide for respiration.
Autotrophs provide sunlight for respiration.
Autotrophs make lactic acid for respiration.
A scientist placed a sample of yeast, a heterotrophic single-celled bacteria, in a closed test tube containing a solution of glucose. How will the composition of the air in the test tube change as the yeast interacts with the glucose?
The oxygen level will increase.
The carbon dioxide level will decease.
The carbon dioxide level will increase.
The level of carbon dioxide and oxygen will remain the same.
