Food Chain Definition Simple

The starting point is the energy from the sun and this energy is traced as it moves through the food chain.

Food chain definition simple. Starting the food chain are producers, which are plants, fruits, and vegetables that make their own energy from the sun. This is because they produce their own food! This is the simplest way of showing feeding relationships.

It shows the flow of energy and materials from one organism to the next, beginning with a producer. A food chain is a linear network of links in a food web starting from producer organisms (such as grass or trees which use radiation from the sun to make their food) and ending at apex predator species (like grizzly bears or killer whales), detritivores (like earthworms or woodlice), or decomposer species (such as fungi or bacteria).a food chain also shows how the organisms are related with. The term food chain describes the order in which organisms, or living things , depend on each other for food.

An arrangement of the organisms of an ecological community according to the order of predation in which each uses the next usually lower member as a food source. For example, a simple food chain links the trees & shrubs, the giraffes (that eat trees & shrubs), and the lions (that eat the giraffes). Then the rabbits are eaten by foxes.

A food chain shows what eats what in a particular habitat. The graphic chain who feeds on who in nature.” Every ecosystem , or community of living things, has one or more food chains.

For example, you could write the food chain for a lion like this: Food chains show the way in which energy is passed from the sun to plants which are then eaten by animals, who are then eaten by other animals, until you get to the top of the food chain. Energy is not created or destroyed.

A food chain in a grassland ecosystem may consist of grasses and other plants, grasshoppers, frogs, snakes and hawks (figure 8.3). This is an organism that makes its own food. Trophic levels and efficiency of energy transfer.
