When the fossil record is examined, one finds some assemblages that are ecologically incomplete. In particular, in some localities there does not seem to be enough plants to support the animals represented as fossils. A model involving transport, sorting and deposition by the waters of the Genesis flood can resolve the dilemma. All living organisms need a source of energy to remain alive. There are many ways whereby they obtain this energy by following various pathways of the food chain.
Plants are by far the main primary producers of food.
On the other hand, carnivorous animals obtain their energy by eating other animals, and a few carnivorous plants eat animals. Because of a variety of energy relationships, the food chain is sometimes referred to as the food web. The food chain can be generalized to the simple fact that almost all animals obtain their energy directly or indirectly from plants. An exception would be the large, 1.3-meter tubeworms that live deep in the ocean along warm water vents where there is no light. Without plants, most other organisms cannot survive.
