A food chain is an idea developed by a scientist named Charles Elton in 1927. He described the way plants get energy from sunlight, plant-eating animals get their energy from eating plants, and meat-eating animals get their energy from eating other animals. The idea of a chain means that all these animals are linked together, so anything that affects one link in the chain affects everything in the chain. ]The key concept that we need to learn from food

chains, food webs and food pyramids is the transfer of energy. For all life on earth there is only one available source of energy, the sun. Furthermore, only plants can change this energy into a form that can be used by animals. All plants rely either directly or indirectly on plants for their energy. Plants feed upon sunlight. Only plants have the ability to convert sunlight into food that they and animals can use. Feeding levels are also called

trophic levels. The word "trophic" is a Greek word for nourishment. To determine the trophic level, we count the number of energy transfers. Green plants are at the first trophic, or nourishment, level because there has been one transfer of energy, from the sun to the plants. The first link in the chain, the plant, is called the producer, while all the links above it are called consumers. For example, look at a simple chain in which grass uses sunlight

to produce sugars and proteins so it can grow. Rabbits eat the grass, and get energy from it. Foxes eat rabbits and get energy from them. Nothing eats foxes, so they are said to be at the top of that particular food chain. If something happens to the grass, suppose a farmer plows up some of the grass to plant a field. Then the rabbits have less food and some of them will die. Then because there are fewer rabbits,

some of the foxes will die, too, even though they don't eat the grass directly. Of course, in the real world, there are no simple food chains like this. Rabbits eat many things besides grass, and foxes eat many things besides rabbits and other things also eat grass and rabbits. When talking about the real world, it is more common to think of food webs. Food chains are still an important concept to understand. In the 1960s, a

pesticide called DDT became popular for its effectiveness in killing insect pests. It was sprayed in small concentrations, so as not to affect larger animals, but it never went away once it was sprayed. Eventually, rain washed it into rivers and lakes, where the concentration was still very small, but this is where the food chain took effect. DDT was taken up by plankton in the water, and accumulated in them. They were eaten by small fish, so each small

fish accumulated all the DDT from the plankton it ate. Then the small fish were eaten by larger fish, and the larger fish were eaten by birds such as ospreys. Each large fish the osprey ate contained all the DDT from everything below it in the food chain, and that magnified the concentration of the DDT in the water by about 10 million times. Ospreys that were affected by it laid eggs with unusually thin and soft shells, and often

An ecosystem is a living community which depends on each member and its surrounding environment Every participant in an ecosystem has an important part to play and if one becomes more dominant than the others, the ecosystem can develop problems. The grazing food chain shows the general flow

of energy in communities. For most ecosystems the model begins with the photosynthetic fixation of light, carbon dioxide, and water by plant autotrophs or primary producers who make sugars and other organic molecules. Once produced, these compounds can be used to create the various types of plant tissues. Primary consumers or herbivores form the second link in the grazing food chain. They gain their energy by consuming primary producers. Secondary consumers or primary carnivores , the
