god has created man. He is only animal who has the sixth sense. But before man there were many other biotic and abiotic things too, suppose, consider a tree is made of wood. when the wood is as a tree, rooted to the ground, it is a biotic component. But, if a man cuts the tree, the wood is no more a part of biotic component, that is, no more a living organism. It's simply a log of wood and wood is abiotic component of nature. See, the tree as a living thing, converts into the non living in just a couple of hours. Nature is just loving and awesome, still it is giving us a plenty. We must love and learn live in harmony with nature.
