How animals would survive or how animals would have evolved if there were no plants?

Animals and plant form ecological system dependent on each other. How would the animal world would have been if there were no plants?

1. Either they would never have been together or they would evolve differently. Nature is technically perfect and adapts by itself. Like a cactus. Also, most oxygen is created from organisms in water. Plants contribute but water is crucial.
2. no question of animals without plants... they are interdependent on each other in food chain.
3. just like u don't have answer for , why people die and where do their aatma go?, there is no answer for this.
4. everyone has to adapt itself according to the environment to survive.. Well this leads to evolution
5. One thing we know is that if an ecological notch that can be exploited exists, then something will evolve to exploit that. Weve recently discovered a bacteria that evolved to eat the by products of nylon manufacture... which did not exist until recent years. Therefore something would have evolved to take advantage of sunlight as an energy source & if the ability to move around was not needed that would have eventually been discarded by the animal... as to wheather it would have the characteristics of a plant rather than an animal is open to debate. http://en.wikipedia.org/wiki/Nylon-eating_bacteria
6. Absolutely none. They wouldn't even have started to evolve.
7. the simple answer is no plants=no animals However.. it is more complex than that. Some of it depends on how you define "Plant" and "Animal". There is most certainly life around the deep sea hydrothermal vents. These areas are not driven by photosynthesis, so there are no "plants" there. It is bacteria creating energy from chemicals in the waters (Sulfides, I think), then creatures feeding off the bacteria, and larger creatures feeding off those creatures, etc. As someone said in another posting. if there is an available niche, Life will fill it if at all possible.
8. every animal would become a carnivore
