Important Of food chains

Without plant life there would be no global food chain. Green plants take water, carbon dioxide and light, and through photosynthesis.Every creature on Earth that cannot create its own food must ultimately consume something that can. In other words plant life.The plant eaters are herbivores, while those that eat animals are carnivores. Omnivores will eat a range of foods, but their existence too rests on the plants, because no animal can produce its own food out of light, water and air. And that is, as they say, 'the bottom line': no plants, no food chain, no life.
