They don't. They produce oxygen. They produce oxygen as a waste material when fusing sunlight, water, and nutrients.
because if we don't have carbon dioxide then there wouldn't be plants and we need plants to survive because they let out oxygen
No, plants need carbon dioxide.
Carbon dioxide is present in the air because plants need carbon dioxide to make food and without carbon dioxide plants would die and eventually the rest of the food chain.
No, because man and animals produce carbon dioxide and plants needs carbon dioxide.
Because photosynthesis is for plants and plants give off oxygen, not carbon dioxide.
The atmosphere and animals breathe out carbon dioxide that plants can use, but it's also partially because plants have mitochondria as well, and by performing cellular respiration they can make carbon dioxide of their own.
because leaves or plants absorb the carbon dioxide
hmm. . because plants and animals are like an persons who lived with carbon dioxide.
because its required for photosynthesis
because it is in the are that travels
Carbon Dioxide is needed for plants to make food.
Plants don't exactly "trap" carbon dioxide, they diffuse carbon dioxide into their leaves through tiny holes called stomata. No, at night plants do not photosynthesize (because they need light to do so) so they have no need for carbon dioxide. Instead, as they still need to respire, they produce carbon dioxide as a waste product from respiration.
