um, breathing
Plants produce oxygen when exposed to light. They do this by the process of photosynthesis. The oxygen comes from the splitting of water molecules to produce hydrogen ions and the oxygen is expelled as a waste product.
They produce glucose and oxygen. Oxygen is given off as a gas.
Any extra energy (food) which is left over is stored as starch
You are a good example of a multicellular organism and Escherichia coli, the microorganism living symbiotically in your intestine, is a good example of a unicellular organism.
why are plants important to people? photosynthesis ============================================================== they give off oxygen which we breath and take in the co2 which we breath out an turn it into oxygen again, if their where no planet we be lucky if their was 5 years worth of air for us to breath.
the process of photosynthesis
oxygen
oxygen-carbon dioxide cycle
Simple answer is, plants breath like any other organism, by day they give out oxygen and at night give out carbon dioxide, ie humans breath in oxygen and exhale carbon dioxide

Plants give out oxygen which the organism in the pond needs
No. Animals do not give plants oxygen. Plants release oxygen as a byproduct of the photosynthesis process by which they take in carbon dioxide and release oxygen. Animals and humans give plants carbon dioxide.
Oxygen is a gas. Trees don't give only rabbits oxygen, they give everyone oxygen. Without oxygen, we would die.
Fermentation is a energy releasing process that does not requie oxygen A example would be lighting/yeast/bread/etc.
It all depends on the plants because plants give off energy to a organism and then that organism gives it to another organism and the process continues.
plants give off oxygen and so do animals and that's how it gets in the air
Trees, because they give off oxygen. Every organism (living thing) needs oxygen to breathe obviously.
