During the day when photosynthesis is taking place and the stomata are open.
during the day
During spring season when there is rapid growth alround.
Carbon dioxide is not normally harmful to plants, as it is the gas that they breath. However, excessive amounts, such as the possibilities that the greenhouse affect might cause, can greatly impair a plant's health. Think of it like Oxygen. We breath in oxygen, but breathing in excessive amounts of high concentrations of it can kill us.
It is most likely oxygen, as plants produce oxygen through the process of photosynthesis. Oxygen is a byproduct of the reaction that occurs when plants convert carbon dioxide and sunlight into energy.
a greater mass of animals than plants
There is air, of course, surrounding Earth, because it was placed there, but any of the elements that combine to make an atmosphere have dissolved or dissipated out into the vastness of space.
they like the sun so the answer is day
During spring season when there is rapid growth alround.
Because plants need CO 2 to process into oxygen. No CO2 = no oxygen production.
Actually, you might be shocked by this, but plants require small amounts of Oxygen. i am not sure why, or any of the details, but they do need oxygen.

The likely word is "photosynthesis" (green plants make food, release oxygen).
the same amount of oxygen produced at 40 degrees celcius
Plants release oxygen .

Algae. Their net release of oxygen is greater than the amount produced by all land-based plants together. Most of the Earth's oxygen is produced by plants, both on surface and under water.
