Then the Garden of Eden would have been a place of total peace, with no predators or prey, just peaceful plants. God [/quote]
Life would be impossible without the predator/prey relationships. Life is a series of mutual dependencies inextricably interrelated. You can’t have plants without herbivore animals, and vice versa.
also, that’s ridiculous. why couldn’t plants exist on their own? they use sunlight for energy… they don’t require something to run around eating them. some plants use this as a competitive advantage and would certainly suffer if all the animals suddenly vanished on the planet. But, with that said, I’m sure many plants would do just fine. [/quote]
Plants use sunlight for energy but they need much than that! Can you thrive on sugar only? Some plants without herbivore animals will overrun the ecosystem leading to soil depletion (lack of nitrogen, potassium, phosphorus). Other plants will die out due to lack of dispersal (a bunch of species have symbiotic relationships with animals that eat their seeds and fruits.) Some plants will overgrown, die and ultimately dead plants matter will pile up…a huge mess!
