Can an organism occupy position in more than one food chain? If so, give an example.

Yes, an organism can occupy position in more than one food chain. For example: If we consider plants which are the primary producers, their presence is necessary in all the food chains because they are the only organisms which can make their own food by photosynthesis. Because of plants only ecosystem is able to exist. If we compare forest food chain, grassland food chain, pond food chain, we will observe that plants occupy the first trophic level of all the three food chains.
