Food Chain Definition Simple

Food chain definition simple. A food chain shows the feeding relationship between different organisms in a particular environment and/or habitat. This lesson will define what a food chain represents, go through specific examples of food chains, and compare and contrast a food chain with a food. Here is another example in picture form:

A series of living things that are connected because each group of things eats the group below…. This is because they produce their own food! For example, grass produces its own food from sunlight.

This is an organism that makes its own food. The definition of a food chain is a system where a small animal is the food for a larger animal which, in turn, is the food for an even larger animal. A food chain in a grassland ecosystem may consist of grasses and other plants, grasshoppers, frogs, snakes and hawks (figure 8.3).

It shows the flow of energy and materials from one organism to the next, beginning with a producer. A food web is made up of several food chains and a food pyramid includes energy flow up the food chain. The starting point is the energy from the sun and this energy is traced as it moves through the food chain.

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. Some animals eat plants, some animals eat other animals. Most food chains start with a green plant, because plants can make their food by photosynthesis.

In the example, grass seeds are eaten. “it is the process by which nutrients are transferred between the different species that make up a biological community. It starts with the primary source, like the sun or hydrothermal vents, where producers make food, continues with consumers, or animals who eat the food, and ends with the top predator.
