Need . me with this.

1. what is the process illustrated above? (the picture)

2. what molecules are released from step one to go to step two?

3. what source of energy starts step one?

4. where does oxygen go when water is split in step one?

5. what molecule comes from the atmosphere to start the calvin cycle?

6. what is the ultimate goal of this process?

7. where do the light reactions occur?

8. where does the calvin cycle occur?

i think the answer would be d

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
