Spaceship San a Maria
An animal have to eat ten times more than a human to get as much energy as a human gets from fruit. So it would be easier if the humans ate the fruit at first.
sun energy carbon dioxide
The flower gets sun energy from the sun, which helps the chemical reaction between carbon dioxide and water. Oxygen and sugar is the result of the reaction called photosyntetis. The plants make their own food which means that they don't have to eat something else.
This is why we think the whole ship should be vegeterians...........
The ship will get oxygen from all the flowers and plants onboard.
