They store it in there robotic cells and transport the energy back to there alien overlords so that they can conqure the world. BUT THAT IS ONLY THE BEGGINING.
THE END
The animals need the oxygen that plants release.
animals usually depend on plants for oxygen. we breath out carbon dioxide and breath oxygen in, same with animals. and plants breath that carbon dioxide in and and breath out oxygen.
Plants supply food and oxygen for animals and humans.
For starters, algae are plants. Plants never use oxygen. Animals use oxygen in the process of respiration. Decomposers use oxygen in the process of respiration when decomposing plants and animals including algae.
animals need oxygen and plants produce oxygen. if there is no light for photosynthesis, then plants can not produce oxygen and animals cannot survive
Oxygen is a product of photosynthesis that is used by plants and animals for respiration.
plants and animals plants=oxygen animals=carbon dioxide
plants so the animals can have oxygen
Oxygen
energy
Both plants and animals use oxygen in their body chemistry. Animals exhale carbon dioxide. Plants give off mostly oxygen during the daylight hours when photosynthesis occurs, but excrete carbon dioxide at night.
Animals do not use up all the oxygen in the atmosphere because plants produce oxygen. When they breathe, plants inhale carbon dioxide (which is what animals breathe out) and exhale oxygen (which is what animals breathe in).
