Food Chain Definition Science

Most food chains start with a green plant because plants can make their food by photosynthesis.

Food chain definition science. Is a diagram that shows how food energy moves from one organism to another in a given environment. It is introduced generally in class 3 science and students get to explore it in detail further till class 9th. A food chain begins with a producer usually a green plant or alga that creates its own food through photosynthesis. Food chain is one of the most interesting topics of science and elucidates upon how every living being is connected together in an ecosystem.

Food energy moves along the food chain when one organism eats another. All energy comes from the sun plants use sunlight to make their own food by a process called photosynthesis. Plants which convert solar energy to food by photosynthesis are the primary food source. Food chain a food chain describes how different organisms eat each other starting out with a plant and ending with an animal.

The food chain can be defined as. In an ecosystem plants and animals all rely on each other to live. A food chain always starts with a producer. This is an organism that makes its own food.

Meaning and definition of food chain. Scientists sometimes describe this dependence using a food chain or a food web. The graphic chain who feeds on who in nature. Food chain the ways in which the organisms in an ecosystem interact with one another according to what they eat for the term food chain may also exist other definitions and meanings the meaning and definition indicated above are indicative not be used for medical and legal or special purposes.

For example you could write the food chain for a lion like this. Food chains are one way to demonstrate how energy is transferred between plants and animals. In the typical predatory food chain producers are eaten by primary consumers herbivores which are eaten by secondary consumers carnivores some of which may in turn be eaten by tertiary consumers the top carnivore in the chain many species of. A succession of organisms in an ecological community that are linked to each other through the transfer of energy and nutrients beginning with an autotrophic organism such as a plant and continuing with each organism being consumed by one higher in the 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. It is the process by which nutrients are transferred between the different species that make up a biological community.
