They dont need oxygen to produce food (Glucose), they use carbon dioxide to produce this but they do need oxygen to respire and get energy from the food that they produuced. The process by which food is produced is called photosynthesis.

Oxygen
Some animals couldn't survive without them because they are food, and if they are vegaterians, that's the only food they eat. They produce oxygen for them to breath, as plants do for humans.
Green plants are the only plants that produce oxygen and make food, which iscalled photosynthesis
None existent. Without plants we would have no oxygen to live by, as the plants produce this. We couldn't eat plants, and neither could any other animals. There would be a shortage of food as cows, chickens, and pretty much anything else dies out. Although this wouldn't matter as we'd be dead from the lack of oxygen. Basically no plants = no oxygen and no food.
Plants produce both food and oxygen, which are needed by animals.
No, humans cannot survive without plants for sustenance and oxygen. Plants provide oxygen through photosynthesis and are a crucial part of the food chain.
