Answer: A. Autotrophs supply food for the heterotrophs.
Explanation: A deer is a heterotroph and a plant is a autotroph. Examples of heterotrophs are animals and humans, and examples of autotrophs would be plants and algae. Therefore, because a deer consumes plants that means that autotrophs supply food for the heterotrophs. And by the way I did the exam myself and got this answer correct!
Answer:
pyruvate and acetyl-CoA
Explanation:
The first step of respiration reactions is glycolysis. When glucose is broken down in glycolysis, the first molecule that is produced is pyruvate. If pyruvate continue to aerobic respiration, it must enter the matrix of mitochondria and be oxidised to Acetly Co-A.
