Bell jar A contains a mouse with a green plant; bell jar B contains a mouse with a burning candle and no plant. Study the diagrams and answer the questions that follow:

Name the physiological process occurring in the green plant that has kept the mouse alive.
Topic: Photosynthesis
Answer
PHOTOSYNTHESIS.
The plant keeps the mouse alive by RELEASING OXYGEN during photosynthesis, which the mouse uses for respiration — while the carbon dioxide the mouse breathes out is used by the plant.
This is PRIESTLEY’S CLASSIC EXPERIMENT, and it is the foundation of our understanding of the gaseous exchange between plants and animals.
THE MUTUAL DEPENDENCE is the point: each organism supplies exactly what the other needs. It is the same principle as keeping green plants in an aquarium, which the 2020 paper asks about.
