Earth survival...What, from the beginning of time would all living creatures have done.?

If we didn't depend on the food chain? would it ever had been possible to survive without eating each other , for example...what would we as humans and animals and everything else have survived if we for example didn't eat cows, sheep, birds etc. Would earth as we know it have survived and if so, HOW?

    We would have to eat something. There are things our bodies require. Collectively they are known as nutrients. We obtain them from food like all animals.

    I am not sure how your question links in to the Earth. It is as it is as a result of the effects the biota has had on it. However, the Earth does not need living organisms.

    Early life was microscopic and survived by eating minerals or chemicals from vents. Some life, like some fungi. survive on water and minerals in rocks. Fungus was on land first, after enough fungus extracted enough minerals from rocks they made a lot of dirt throughout the generations, then plants thrived. Animal life can eat both fungi and later plant material, and when enough herbivores filled the land the carnivores evolved.

    Prototaxites was an early giant fungi which helped shape the terrestrial world we have today.
