Do we have any choices? If not i would say that they may be used in feed for animals not genetically modified, causing them to be non-organic. If you grow crops with a GMO fertilizer, it will affect them as well.
<span>The main difference between a community and an ecosystem is that the ecosystem is defined as the result of what happens when a community of living organisms shares and interacts within their environment. What this means is that the ecosystem is a product of a specific community. There are several types of ecosystems, for example, a marine ecosystem, the rain forest ecosystem, the swamp ecosystem, and the desert ecosystem, just to name a few.
Hope this helped. :)</span>

Explanation:
Australopithecus (first ape-man): Australopithecus is considered as the connecting link between apes and man as they shared the characteristics of both. The fossil records shows that they appeared around 5 million years ago. <em>Australopithecus africanus</em> was about 1.5 meters high and had human as well as ape like features. It was with bipedal locomotion, omnivorous in their diet and had erect posture. It had human like teeth with small canines and large chewing teeth. The brain was more like an ape with the brain capacity of about 500 cc similar to that of an ape. He lived in caves, had projected brow ridges with no chin. Its believed that <em>Australopithecus africanus</em> gave rise to <em>Homo habilis</em> about 2 million years ago.
The earliest species of Homo genus is <em>Homo habilis</em>. They were skill full man also called as handy man or the tool maker. He had erect posture with bipedal locomotion. The teeth were like modern man. He was skilled and made tools with stones. Slowly with evolution the prognathous face changed to orthognathous in cro magnon (<em>Homo sapiens fossilis</em>).
